How do I customize the second color by entering an RGB value?
A. There are 2 ways: 1. Right-double-click the solid color buttons or the color pallette, and the color dialog box will open. Enter an RGB value for the second color; 2. Click “Color Exchanger” to exchange the current color for the second color; Enter an RGB value directly into the RGB box, or drag the RGB/Brightness Sliders to change the color. Finally, click “Color Exchanger” to exchange the second color back.
