Rainbow

This tutorial will show you how to make a rainbow in Paint Shop Pro.  If you don't want to follow the tutorial, I have a rainbow script that I released two years ago.

1.  Open up a new canvas that is the same width and height.  My canvas is 1200 x 1200.

2.  Use the custom selection tool to create a 1200 x 100 selection across the bottom of the canvas.

Left = 0
Right = 1200
Top = 1100
Bottom = 1200

3.  Fill the selection with the color, gradient or pattern desired for one band of the rainbow.

4.  Use the custom selection tool to create a 1200 x 100 selection above the previous selection.

Left = 0
Right = 1200
Top = 1000
Bottom = 1100

5.  Fill the selection with the color, gradient or pattern desired for one band of the rainbow.

6.  Repeat  step 3 and step 4 another 3 more times for a rainbow with 5 bands. I have included screenshots of the custom selections for each repeat.

Left = 0
Right = 1200
Top = 900
Bottom = 1000
 

Left = 0
Right = 1200
Top = 800
Bottom = 900
 

Left = 0
Right = 1200
Top = 700
Bottom = 800
 
7.  Ctrl + D to Select None.

8.  Use the Polar Coordinates effect (Effects > Distortion Effects > Polar Coordinates) to create a circle out of the selections.

Rectangle to polar = Checked
Edge mode = Transparent

9.  Crop the canvas to half the size of the original.  Choose the upper half of the canvas.

The rainbow is now complete.
