there's some confusion here. someone recalls it as agave. however,
agave is a tool to aid you in finding hopefully pleasing and aesthetic
color combinations.
It is Agave : http://home.gna.org/colorscheme/
agave is based on some fundamental research that happened towards the
end of the 19th century and through 20th century on human cognition
and perception of color, specifically on work done by a.h. munsell,
and then by johannes itten, not counting several other researchers
including a german researcher who took the work of newton and munsell
even further.
pradeepto mentions color management. this is quite different from
color-combinations. color-management is a science, and is explained
further down.
the first step to color-management is color-calibration.
color-calibration is all about tuning your device to input, display,
or output the right colors. think of color-calibration as the art and
technique of tuning your guitar so the strings are in tune. then go
ahead and tune in all the other instruments in your band.
the tool for color-calibration under foss is called LProf.
this tool is leaps ahead of the color-calibration tool that ships with
adobe, called 'adobe gamma', that sits in the control panel of your
mac or windows operating system. http://lprof.sourceforge.net/
think of color-management as the more complex science of
understanding how to tweak your microphones, mixers, recording
equipment, and finally, your mix-down, so your music sounds the same
(or similar) on anything from a 5.1 surround sound home theater
system, an open-air concert, in-ear headphones, television broadcast,
fm radio, am radio, plus all kinds of radio devices, various levels of
mp3 compression, DVD-audio specs, mobile ringtone, and even blared
through a cheap megaphone in a crowded market.
the color management engine under foss is called littlecms, and in
terms of engineering it outclasses apple's colorsync and microsoft's
ICM engine. http://www.littlecms.com/
always surprises me how color is so easily understood when explained
with analogies from sound. this again thanks to the groundbreaking
research by hermann von helmholtz from the 19th century, on
physiological psychology. http://en.wikipedia.org/wiki/Helmholtz
pradeepto, hope this helps, and do share with us what you intend to do.
