{abright} Not Respected for Tint Changes in Images

Tint: ({abright} == true) and 'ffffff' or '45ec1a'

Expected behavior: Should evaluate to ffffff (white) when bright and 45ec1a (green) when dim. When bright again should revert to ffffff.

Defect: The first time, it properly evaluates to ffffff. When dim, properly changes to 45ec1a. When brightened again, it fails to evaluate to ffffff. Tint remains green when should be white.
