Try saving the color table before you call cgColor, then restoring it after the call

tvlct, r, g, b, /get

x = dindgen(10)
plot, x,x, color = cgcolor('red')
plot,x,x, color=cgcolor('green')

tvlct, r, g, b

colors=bytscl(x)
plot, x,x,/nodata
for i = 0, 9 do plots, x[i],x[i], color=colors[i]
colorbar
