[vslist] Linear Colourmaps

Hi,

I am trying to find out about the perceptual linearities of
colourmaps - specifically how to check if a particular colourmap
is perceptually linear, and if not, how to achieve it.
By perceptual linearity, I mean that the perception of a linear
scale represented by specific colourmap is also linear and
is not affected by colour-transitions. E.g. a basic RGB colourmap
will have some perceptual boundaries between the major colours.
(Though I guess this is also data dependent).

If anyone has any pointers to articles, references, books,
websites etc I'd be very keen to hear about them - I'm finding
it difficult to locate any decent starting points.

I hope I've managed to be explain this correctly - I'm only
just starting to look at this field!

Many thanks in advance,

Matt
