Aaon white	4.25:1	fail	pass	fail	AA: use #2d8653 as the text (4.52:1) AAA: use #21633e as the text (7.19:1) AA: or shift the background to #0f0f0f (4.52:1)
Aaon black	4.95:1	pass	pass	fail	AAA: use #39ac6b as the text (7.29:1)

Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with seagreen as the background.
