Color Properties: Hue, Tint, Shade, Saturation, Brightness, Chroma

Color Properties: Hue, Tint, Shade, Saturation, Brightness, Chroma
In this section we have a look at the terminology of color properties and their meaning in different contexts. Color properties allow us to distinguish and define colors. The more we know about color properties, the better we can adjust colors to our needs. Hue Hue defines pure color in terms of "green", "red" or "magenta". Hue also defines mixtures of two pure colors like "red-yellow" (~ "orange"), or "yellow-green" (limitations to this statement will be addressed later). Hue is usually one property of three when used to determine a certain color. Hue is a more technical definition of our color perception which can be used to communicate color ideas. Hue ranges from 0° to 359° when measured in degrees. Hues are basic colors we learn to connect with words as children. Hues can refer to the set of "pure" colors within a color space. Tint Tint is a color term commonly used by painters. A tint is a mixing result of an original color to which has been added white. Other usage / meanings of tint: Shade

Tips for using color in maps If you've found yourself on this page, we're assuming you've Color Theory and Mapping It’s important to realize how much your choice of color on a map can affect the story you are trying to tell with your data. Data Visualization vs. Data Analytics The term Business Intelligence solution can be a deceiving one. Many software solutions that call themselves BI can actually only offer you half of what you need. Here it’s important to make the distinction between two types of business analysis and intelligence tools: end-to-end solutions and ones that are merely front-end. An end-to-end solution is made up of a platform back-end, basically the tools and algorithms that handles preparing all the data, and a front-end that creates data visualizations and dashboard reporting. While we like to see our data in easy to handle visualizations, platforms that only give you this are not enough to get real insights from your company’s data.

Glossary of Color Terms * Chromaticity: Think about a color's "purity" when describing its "chromaticity" or "CHROMA". This property of color tells us how pure a hue is. That means there is no white, black, or gray present in a color that has high chroma. These colors will appear very vivid and well, ... pure. This concept is related to and often confused with saturation. However, we will continue to use these terms separately because they refer to distinct situations, as explained here. Cartographic Design - GIS Wiki From Cartographic design is the visual representation of geographic and spatial information on a map.[1] The purpose of Cartographic Design[2] is to create a map that is visually appealing and effectively communicates pertinent information to the audience.[3] Cartographic design consists of planning and layout.[3] During preliminary designing phases, the cartographer determines the elements that will enhance the map's purpose.[4] As a mapmaker begin composition of maps, the basic elements need to be worked on, such as the subject area, the title, the legend, the scale indicator, color schemes, the north arrow, labeling/supplementary text, frame/border, and insets. A map does not always contain all of these elements. [5] Cartographic design is subjective to the cartographer's idea of a "good" map.[6] “We all know that there are good maps and bad maps, the problem is defining which is which.

Data-driven Insights on the California Drought (12/8/2014 8:33:13 AM) A newly released interactive California Drought visualization website aims to provide the public with atlas-like, state-wide coverage of the drought and a timeline of its impacts on water resources. The U.S. Geological Survey developed the interactive website as part of the federal government's Open Water Data Initiative. The drought visualization page features high-tech graphics that illustrate the effect of drought on regional reservoir storage from 2011-2014. For the visualization, drought data are integrated through space and time with maps and plots of reservoir storage. Reservoir levels can be seen to respond to seasonal drivers in each year.

Color Theory For Designers - Concepts And Terminology If you’re going to use color effectively in your designs, you’ll need to know some color concepts and color theory terminology. A thorough working knowledge of concepts like chroma, value and saturation is key to creating your own awesome color schemes. In Part 1: The Meaning of Color1 of our color theory series, we covered the meanings of different colors. Here, we’ll go over the basics of what affects a given color, such as adding gray, white or black to the pure hue, and its effect on a design, with examples of course. Hue Link

The GIS Encyclopedia From Color or colour is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, green and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color plays an important role in geospatial science and technology, especially in Cartography and Remote sensing, due to its ability to convey qualitative and quantitative information. Thus, the proper understanding and use of color is crucial to the creation of visual representations that clearly portray aspects of the real world with minimal confusion and misinterpretation.

Molecular clouds show off potential, beauty of data visualization “Simulated molecular clouds are beautiful, intricate, and ever-changing — properties that make them ideal candidates for high-powered visualization,” wrote Erica Kaminski, a PhD student in the Department of Physics and Astronomy, when she submitted these winning images to the data visualization contest sponsored by the Health Sciences Center for Computational Innovation (HSCCI). The contest helped showcase the capabilities of the new VISTA Collaboratory in Carlson Library — and in this case the Center for Integrated Research Computing’s Blue Gene/Q system, called Blue Streak, which consists of 1,024 nodes,16 TB of RAM, and 400 TB of storage. A molecular cloud (or stellar nursery if star formation is occurring within it) is a type of interstellar cloud whose density and size permit the formation of molecules, most commonly molecular hydrogen — in contrast to other interstellar areas that contain predominantly ionized gas.

Color tools for map makers By Aileen Buckley, Mapping Center Lead My friend and one of my mentors, Dr. Duane Marble, recently shared this story with me: Years ago I met a consultant in Sydney who related a story of being fired half way thru a client presentation since the CEO claimed he was trying to make a fool out of him by pointing to things (suggested store locations) that were not shown on the map. He found out later that the CEO had a rare form of color blindness. Duane then suggested we post on Mapping Center some tools that map makers can use to be a bit more careful in their color selection.

Visualized 2014 Roundup Videos from the 2014 Visualized conference in New York City were posted late last week. Shortly after the conference last January, I wrote 8 separate posts summarizing my observations about data, storytelling, aesthetics, and other aspects of data visualization and presentation. In case you missed those posts, I’ve compiled them together below. Choropleth map - GIS Wiki From The US Presidential Election of 2004, visualised using a choropleth map A choropleth map (Greek choros-space & pleth-value) is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. Each color is associated with an attribute value. This value is typically quantitative. The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region.

Of all the forms of non-verbal communication, the most instantaneous method of conveying messages and meaning through visual cues is color. In our design work, we use white space, typography and color theory to create and support the information architecture of a composition or a story. Information layering—organizing large amounts of data into short, digestible chunks—is a method for providing multiple points of entry into a story package, presentation, or layout. Color not only helps highlight or reinforce the information architecture of a layout, it can also set a mood, evoke an era or time period, or induce an emotional response to the information often unique to any given individual.
