Colour tips

I've found that matching a range of contrasting colours is quite tricky. This shows how I've found a pretty cool solution. I tried @Erica Schoonmaker's trick and while it did produce cool results, the colours i was seeing weren't as good as I wanted.

I tried adjusting the colours so that the greyscale hue's matched (almost exactly) and voila!

I use 2 screens that are setup very differently (1 is high quality and the other is purposely poor) so I can easily see varying results.
