part 1,2 and 4 have a green rectangle, and no magenta on the right hand side, but what happened here? did you paint the green blue and then green again, to enrich the colour?

nah, just careless photography with a window off to the right at different times of day. it's red, yellow, and limish green.

i'm inspired by the magenta and red combination.. tnx.. i think i might do some work along those lines :)
