Roan
From The Wajas Wiki
Roan is a unique Custom Marking that covers the entire waja in the chosen color, but the color will have the appearance of being half its actual opacity. Therefore, a pure white waja with pure black 100% strength roan will look grey, a pure white waja with pure red 100% roan will look pink, etc. Any markings layered under roan will be partially visible.
See Soft Roan for the Roan coat pattern marking.
Marking Appearance
All examples feature wajas with the marking in FF0000 (pure red). However, this marking can come in any Hex Color as well as rainbow (simply put the word "RAINBOW" in the hex field) and chrome (simply put the word "chrome" in the hex field).
