No no no, you made it purple because that is the best color there is! (Says the purple robot and bunny-girl)
I am a tiny bit confused however as to the source of the purple goo - Not you Palomine - as it sort of appears suddenly. I keep thinking that it was from the purple armor gal but now I am not so sure as her abilities appear to be black in nature...
Anyway a bleak purpleish landscape interesting... Starts me thinking about a particular bunny-girl still stuck in such a land... hmmm.
Keep up the good work!
On the newest page? Evilyn's beam is black with a purple aura around it. I'm assuming everything it hits turns purple (maybe only coated with something that can be cleaned off). All of the stuff on the ground are the leaves and brush that was destroyed by her blast.
She's a little like Cyclops from the X-Men, except it's that she always fires at full-power. The visor is just meant to help her limit the strength of her blasts. She can also steer them (as was kind of shown), but without being able to see where she is shooting, her blast was moving slowly enough to be shot by the robots. That made the blast which must be pretty unstable explode.
Maybe her visor also has cameras that allow her to see what the twins and the robots see? That would allow her to shoot crazy beams around things.
