I need to get the contrast color for a text foreground using the background color and contrast ratio between colors.

Example: Background - Colors.Red Contrast ratio - 7.0

With the above inputs, I need to calculate the foreground color.

Is there any formula available to get this?

Is there anything about _this question_ that specifically relates to C#? This seems like a general colour theory question. – ProgrammingLlama Aug 10 '22 at 06:28
@DiplomacyNotWar, Yes this is related to color theory. As I needed to implement this logic in C#, used that tag too. – Karthik Raja AKR Aug 10 '22 at 06:30
how is this a programming problem? – Piglet Aug 10 '22 at 06:50
