onChange triggered when sliding Hue slider on SketchPicker
Hi,
I'm using SketchPicker from `react-color` package. When I slide on Hue slider, onChange method is triggered, and it is not what I want. Shouldn't this slider only change colors in palette above, and then with cursor, user can select desired color from palette? How can I disable onChange trigger on this hue slider?
