In my workshops I always have students paint a simple color scale. Yes, you can buy those but that is just pathetic, isn’t it? You’re a painter, you should be able to paint one.
Inevitable, someone will pick a color like yellow ochre, or worse, a yellow to paint a value scale. Why is it not working?
The short answer is: because the color yellow is too light to paint a scale from 1-10 with.
The strongest yellow is still only a light value..makes sense?
Black, blues, violets, warm and cool greys work.
To determine a color’s own value in it’s strongest application, it helps to make a value/color comparison chart.
Ideally you should know the value of the colors on your palette.
Take a look at the image. The chart is a neutral grey value scale on top (numbered 0=white to 9=strongest), where all the different colors underneath are placed to match the value above. (as good as possible) Every color is applied in it’s strongest value, out of the tube.
From left to right(second row):
perm alizarin, Ultramarine blue,
Quin Rose, Ultramarine violet
Quin red, cobalt blue
Cad red, burnt sienna
Cad orange, raw sienna
Indian yellow (interchangeable with Yellow ochre?)
cad yellow light
cad yellow medium
It helps to know that, while red is certainly strong, it’s strongest value is maybe a five, if the white of the paper is a 0. Worse with yellow, that’s really only a 1, no matter what you do.
When introducing new colors to your palette, place them in the right spot so you know what value strength it has!
Some painters even make a value scale in neutral on the side of their palette! That way it’s easy to compare your color mix to the scale next to it.
