```Hello,
Something like,

redchannel == RandomInteger[{1, 255}, {96, 96}];
greenchannel == RandomInteger[{1, 255}, {96, 96}];

GraphicsRow[{ArrayPlot[redchannel,
ColorFunction -> (RGBColor[#, 0, 0] &)],
ArrayPlot[redchannel, ColorFunction -> (RGBColor[0, #, 0] &)]}
]

How would one convert a grey scale image into another color
scale?

By "another color-scale" I mean rather than rendered in shades
of grey, rendered in shades of a different color.

Many thanks,
Jason

In case you were wondering why I am asking:
I am attempting to use Mathematica to analyse microarray data.
The capture software outputs multi-image tifs.
One image represents a green wavelength, another image
represents a green wave length. But they are rendered in grey
scale. These images get combined to give a ratio of the two
wavelength, but for that to work, they have to be converted from
greyscale.
