Jane Blundell: Watercolour Comparisons 7 - Yellows I have posted about mid yellows in a primary triad palette, but here I will show comparisons of a full range of yellows, including warm and cool yellows. I will post about earth yellows separately. I have also added all these and more to my website so you can compare them here. You have the choice of opaque or transparent yellows, with the very popular cadmiums being more opaque. You also have the choice of single pigment and mixed pigment colours. I use single pigment colours where possible. DIY122 – Make a LED Christmas Tree!

Everytime we come across them, we are filled with admiration: Admiration for the skill of the master craftsman, as their creator, but also admiration for the balance between function and beauty, which turns the furniture or temple into a work of art.
