Ok Picker

A toy application to test egui programming. This application will be a color picker based on the Okhsv colorspace by Björn Ottosson, with:

• A 2D picker in the SV space,
• A 1D picker in the Hue space,
• Buttons to increment/decrement any single value of the HSV triple,

And as stretch goals: - Buttons to add/remove colors to a palette, - Contrast between each color of the palette and a chosen background color, - A palette generator that auto-picks colours starting from 1 or 2 colors and a set of rules: + Just the foreground color + A foreground and a background color + A foreground and an accent color
