I didn't particularly like the look of the current color picker, so I decided to make my own. You can hook into it by using Apollo.GetAddon("IronColorPicker"):ShowColor(value, callback), value is a hex string for the color you want to show, and callback receives a table. The table returns HEX, R, G, B, H, S, V, all accessible through tReturned.HEX, etc.
