Description

Hi Everyone, I want to share this Bicolor version of The Dragons of Ara. For this one, I did not use a strictly bicolor HOO palette, instead I mixed a little bit of Sii in R and G channels for more chromatic richness.

The color mapping was: R:Ha*0.7+Sii*0.3, G:Sii*0.2+Oiii*0.8, B:Oiii

I hope you enjoy it, clear skies!
