I agree. In spite of the fact that the documentation does not say that you can specify a multiple color, this looks like a (dangerous) bug.

IDL> pl=plot(/TEST)
IDL> toto = 'blue' & p2t = text([0.3,0.3,0.3, 0.3],[0.8,0.77,0.72,0.69], cols, FONT_COLOR=toto)
IDL> foreach t,p2t do print,t.font_color
0 0 255
0 0 255
0 0 255
0 0 255
IDL> p2t = text([0.3,0.3,0.3, 0.3],[0.8,0.77,0.72,0.69], cols, FONT_COLOR=cols)
IDL> foreach t,p2t do print,t.font_color
