Question
I would like to know / calculate color codes of N red shadows (N can be 5, 20, or 50, for example).
How could I do this ?
I noticed, for example, that the following gives some red shadows:
- R = 255, G = B = 0..255
- R = 0..255, G = B = 0
Is there any known method to calculate shadows ?
Solution
I think it would be easier to generate the shades of a color in HSV color-space. You can choose a base color (hue) and variate the saturation or the value, and then generate the RGB values for the generated colors. There is a nice wikipedia article about the HSL/HSV color space, where you can find the formulas to convert colors from RGB to HSV and back.
