Request Feature...

Either: 1) Give Access To Common SASS modules/methods.

If I am using a primary color for my themebuilder customization and define it as

$my-primary-color = #2a3bd1,

give me the ability to use functions in sass like

• lighten($my-primary-color, 20%) or
• color.change($my-primary-color, $saturation: 50). 
• However you do it

Or: 2) Provide swatches using the current theme colors on color picker.

Or create swatches from the current theme color in the color picker to use as starting points when picking another color representing hover or selected or disabled, etc.
