Tool Editor
Flow’s Tool Editor is the place where you customize size, type, and color. When you’re drawing, the Tool Editor displays as a compact size with controls to quickly adjust the size and hue of the current tool. When expanded – either by tapping the tool icon at the top, or the selected tool in the tool dock – it shows detailed controls for customization.
By default, the Tool Editor is placed on the left side of the screen; however, you can switch it to the right side by pushing the Tool Dock toward the edge of the display.

Swipe up or down on the vertical strip of colored bars to spin through the spectrum of color hues.
Color Grid
Tap the icon at the bottom of the editor to open the color grid, which provides a quick way to adjust the brightness and saturation of the current tool.

Slide the strip of color left and right to adjust saturation.
If you slide the saturation all the way down to the end of the tool, you can change the mode to shades of gray. Slide back left or tap back on the color area to return it to color.
Brightness
You can change the brightness by swiping up or down on the end cap of your selected tool. Change the brightness to zero to swap to shades of grey.
Eraser
The Tool Editor is also where you control the eraser. In the compact Editor, you can select the stroke or normal eraser and further options for each.
Eyedropper
Finally, the Tool Editor also contains an eyedropper tool. To use the eyedropper, press and hold on the current color on the compact Editor and drag over colors on your document you want to match. You can also drag over another tool to match its color. Once you release your finger, the color you’ve just selected will be applied to your current tool.
