For a traditional approach to digital color, use the Classic Color Picker with Hue / Saturation / Brightness sliders.
Choose a Color
On the right hand side of the top menu, you’ll see the Color Button. Tap on it to open the Color Picker, then tap the ‘Classic’ tab at the bottom of the popover. Procreate will remember your preference in future.
Classic Color will be familiar to veterans of digital art.
Adjust the saturation and brightness of your color by moving the reticle around the rectangular color field. To change hue, use the first of the sliders below.
Hue / Saturation / Brightness Sliders
Adjust your color choice using the HSB sliders.
The first slider adjusts hue, the second controls saturation, and the third changes brightness.
The rectangles top right above the Color Disc display your active and secondary colors.
Once you’re happy with your chosen color, tap anywhere outside the Color Panel to close it.
