Customization: Color Selector

[32teeth]

Description

in the settings section under themes in addition to being able to select one of the existing themes we should have a 'custom' theme when the use selects it is presented with an RGB slider. On changing the RGB slider we update the current theme.

AC

• RGB Slider
• Load in the current theme and set the HEX (base color) to the RGB slider values
• When the user change the slider, update the theme colors
• Press B to cancel (restore the previous theme)
• Press A, confirm and save the HEX to the settings
