I recently downloaded Adobe sketch to use on my new iPad Pro. Each of the tools seem to have colors already assigned to them that I cannot change. I've tried EVERYTHIN. Please help me out.
To get to the color palette, tap on any of the brushes in the toolset. That will open a Color menu. To get to the Color Picker, tap on the Color circle in that menu. Tapping opens the Color menu. With tabs for Picker (a color wheel), Themes (a handful of preset color themes in the app) and My Library (color assets from Adobe Capture CC).
To change your brushes, long-press (press and hold) on any of the brushes in the toolset. That will open the Brush menu with tabs for App Brushes (the app's brush selection) and My Library (brush assets from Adobe Capture CC.
