Kivy rgba (0 - 1) vs. regular rgba (0-255)

[Ao Yen]

Hello all,

So when setting a Color property using rgba in Kivy we need to use a value between 0 and 1.
For my application design I often refer to Adobe's Kuler website to find complementary colors.
Adobe also provides HEX values for colors and I understand that Kivy-utils has a function to convert this to Kivy rgba 0 - 1.

Can someone contribute about the relationship between 0-1 and 0-255 rgba? I've looked at the OpenGL website for this but to be honest
anything beyond pure basic graphics instruction computer science is above my amateur knowledge level.

The 0-1 value is just the 0-255 value divided by 255. E.g. on the 255 scale, 100 would equal 100/255 = 0.392... on the 0-1 scale.

There's nothing very special here, just different places use different conventions. Kivy (and opengl) use the 0-1 convention, so just convert your 0-255 values with a simple division.

Well that was easier than expected. Thanks!
