Unfortunately, the axis color and the axis label are not separated in
the underlying Plot and Axis commands in IDL. That's why you have to do
this run-around.

In object graphics, these two colors are separate, so you can do what
you like. It's rather round-about in Function Graphics, too, but it is
possible. You do it like this:

;***********************************************************
im = image(cgdemodata(7))
p = im.POSITION
p = plot(indgen(360), position=p, /current, /nodata)
axes = p.axes
for j=0,3 do axes[j].color = 'white'
for j=0,3 do axes[j].text_color = 'black'
;***********************************************************

Cheers,

David
