I have a color and I want get a tint of that color by a certain percent. So 100% is the color itself, 90% is a slightly lighter color, etc. Basically, it's like adding 10% of opacity to the color, if the color is on a white background. I need to convert the color into a hex HTML color value, so I don't want transparency.
Is there an algorithm to get a tint of the System.Drawing.Color RGB value?
Yep there are a lot of different ways to do this. One way would be to convert from RGB to HSB (Hue, Saturation, Brightness) and then crank the brightness down some percentage.
