Description

Bi-colour HOO blend with RGB captured for star colouring. I'm learning some Pixel Math magic and was helped by the Pixel Math tutorials from 'Old Wexi', Gerald Wechselberger - thank you.

I'm not confident of the final rendition and wonder whether it appears too pushed - comments welcome.

Also synthetic green version - hhhmmm . . . really not sure.

Clear skies! Barry
