Red line - I take it you mean Vmca rather than Vmo is 77kts
Blue line - on the CASA is Va (maneuvering speed) and that is 146kts
What is more important is Vr and V2 which are worked out on the charts for the different A/C weights, but ballpark Vr is about 90kts and V2 is about 98kts
90 is also the approx approach speed with full flap, dont want to be any faster than that when you touch down cause the reverse wont work till your below it.
