# What would a terraformed Mars look like from Earth?

Question in the title. Currently, Mars is a small orange dot in the sky. But what if green, blue, and some white were added? I wouldn't expect it to be too different- a large portion of it will remain pretty much the way it was, but with more snow (Tharsis bulge is REALLY high up).

Mars currently has albedo 0.250, 81.7% of Earth's somewhat brighter 0.3. A terraformed Mars would presumably have a similar albedo. That would make it slightly brighter and bluer, about 0.2 ($2.5\log_{10}(0.3/0.25)$) magnitudes brighter. But this is not going to change the overall magnitude ($\approx -3$ at most) much.
