However, sometimes it is useful to compare different geometries. In crystal field theory, it can be shown that the amount of splitting in a tetrahedral field is much smaller than in an octahedral field. In general, Δ t = 4/9 Δ o.

So green is absorbed, and the complementary color of green is red, so red is the color of the complex. It would be high spin. The complementary color of violet is yellow, which has a wavelength of 570 nm.
