RGB Helper

RGB Helper is a lightweight Visual Studio Code extension that makes working with RGB values easier. It automatically normalizes RGB tuples in .css and .kv files to the [0.0, 1.0] range and adds an alpha channel 1.

With RGB Helper, you no longer need to manually calculate normalized colors — just type your RGB tuple, and the extension will suggest the normalized version.
