I’ve hit this “issue” myself, too :slight_smile:
There are ‘2’ kinds of Color variables in Unity. Color and Color32. Color is in the range 0…1 and is a float. the syntax you’re using is for Color32. So, you can choose to alter it how you’d like so it works :wink:

Just as an aside, the benefit of Color in the range (0…1) is that it can represent a position on a gradient. I use this to flicker softly between yellows and oranges for flames. Color32 uses (0-255) values for RGBA.

And to add, you can simply divide your value by 255 to get the float you want.

So if G = 75, just do G/255.
