How do I create my own color gradient?

Hi All:

Kinda of a silly question, but I've been banging head against the wall
for the past two nights. I am trying to figure out how I can make my
own colour gradient, analogous to Rainbow, AplineColors, &c.

Is there any standard framework around trying to create your own?
Further, say I wanted one of the preexisting ones, but scaled
exponentially, or set a particular value to bright yellow (to
highlight that specific result). I used to use IDL quite a bit, and
made use of these kinds of manipulations frequently.

Any ideas or references? I keep finding myself doing the same old loop
in the Documentation Center, from ColorData, to ColorFunction, and so
on, and so on.....

Cheers,

t.
