Don't be afraid to let the temps get a tad above 70. Stay under 80, but not too cool at night, until the last 1/2 or 1/4 of flowering. Then the colors will come anyhow - if you're letting the temps get really cool at night.
Because we have a perpetual harvest, we never let the temps get too cool. Cool root zones often stunt growth. You see those somewhat long, skinny tops on the main buds? That's probably a result of low temps and slight stunting as a result. No big deal though.
