Since it's not flaming orange-red I'd go with 'Radiance'. Here 'Radiance turns bright pink, not quite bubblegum, and 'Kaleidoscope is the aforementioned bright orange-red, at least in full sun. I have a 'Kaleidoscope' at home in mostly shade and it is green and chartreuse. The ones at work on the west side of a metal building really glow. Pictures to follow when the sun comes up.
