Test it.
Does anything change using Alastair's script?
Do controls or essential images disappear?
Is the print readable.
Now, Alastair doesn't include this step but I have found it useful.
Reverse f and b. That is test with the foreground/ background pair (b, f).  Look for the same stuff."

AC: It occurs to me that the easiest way might be a test like:
Change the colours to black on white, where the foreground text is changed to white from a dark colour, or black if they are light colour.

So if the text is light on dark you change to black on white, and if it is dark on light then change it to white on black.

And just to emphasise, this would be a test to find issues, only a proxy of what the user does, not the user requirement.

Cheers,

Alastair
