Shortly is there any way for GetPixels to return pixels colour in hex format? and then ofc Set it also by passing hex values?
You’ll need to write some sort of utility method to convert between hex and RGB. Luckily someone has already done so and it’s available on the wiki:
Using the C# version of http://wiki.unity3d.com/index.php?title=HexConverter
as extension methods for Unitys color could eventually do the trick.
