Keep colours exactly as they are added

Right now, Howspace saves colours as HSL, which means that a colour input made in RGB or HEX might change after saving settings (RGB has 4x the colour variations of HSL).

Now, this might not be a significant difference visually when looking on a computer/mobile screen, but it can be confusing. Could colours be stored exactly as they are added, or could the logic be changed so that they're saved as HEX or RGB?
