Color palette generator for charts

I created this widget to generate a custom palette starting with one hue selected by the user. The palette will contain ten colours, distinct enough to accommodate different types of charts (sequential, qualitative).

To cover most types of charts for the MVP I chose a divergent scheme algorithm - three hues equidistant on the colour wheel. The palette is achieved by generating two gradients, one going from the hue selected to a lighter or darker version of it, the second going from the second equidistant hue to a third equidistant hue.
