like if you wanted to mix paint to get a color from a computer would you do the opposite of what the RGB value is? I’m confused
like if I wanted to take the RBG code R:99, G: 66, B, 33 wouldn’t it look more lightful than if I mixed paint into 1 part blue, 2 part green, 3 part red? how would you paint a color code?


There is a difference between colors you see from reflections, and from a direct source.
Your t-shirts is light hitting them, and reflecting back to your eye. Depending on what is reflected and what is absorbed, you will get a colour.
But that will not be the case from screens that emit their own light.
