Click the Set Colour button next to the parameter for which you wish to change the colour.
The standard Color window displays:
Select a standard colour in the Basic colors section.
If you then want to have a lighter/darker shade of a standard colour, click the colour, then drag the slider on the far right up or down, or click on the graduated bar until the shade you want is displayed in the box. If you wish to save this colour for the duration of your current computer session, click the button.
You can also select a colour by clicking in the colour palette, or by entering numbers in the area to the bottom right. You will notice the box above changes colour.
If you are not selecting a basic colour, and wish to set the same colour in another provider's book, save it as a custom colour.
NOTE: It is prudent to write down the Red, Green and Blue colour settings numbers, in case the custom colour is overwritten or not saved ("Add to Custom Colors" only works for the current computer session).
