# Math Help - Colors

1. ## Colors

For example if red color means I have to reduce the intensity gradually and i have to create minimum 5 shade colors of red.

Anyone help me How to do color shades, any algorithm is there?

You could start by saying how you are representing colour (probably 24 bit, 8 bits per channel for RGB, but if you do not say so we are only guessing).

$\alpha [255,0,0] + (1-\alpha) [255,255,255]\ : \ \alpha \in [0,1]$

rounded to the nearest integers in $[0,255]$
