RGB-to-Hex Color Converter RGB-to-Hex Conversion Question: How do I convert RGB values of a color to a hexadecimal string? Answer: The RGB-to-hexadecimal converter algorithm is simple: make sure that your values are in the range 0...255, convert R, G, B to hex strings, and then concatenate the three hex strings together. function rgbToHex(R,G,B) {return toHex(R)+toHex(G)+toHex(B)} function toHex(n) { n = parseInt(n,10); if (isNaN(n)) return "00"; n = Math.max(0,Math.min(n,255)); return "0123456789ABCDEF".charAt((n-n%16)/16) + "0123456789ABCDEF".charAt(n%16); } Notes: The script parses the input R, G, B values as integers using the standard function parseInt(string,10); the second, optional argument 10 specifies that the value must be parsed as a decimal number. RGB/hex codes for named colors supported in most browsers are listed below: See also:

What You Need to Know About Building a Mobile App for Your Brand In case you haven't noticed, most of your potential customers have gone mobile. Last June, consumers began spending more time on mobile apps than on the web, according to researcher Flurry. Earlier in the year, Mary Meeker, a partner at Kleiner Perkins Caufield & Byers, released a report showing that combined sales of smartphones and tablets overtook PCs for the first time.

How much have prices come down? Mind you, that's the average cost. iOS or Android? Now that your expectations are more grounded, it's time to take a look at your options.
