Color Case Studies
[Author: Bill Fischer]
Overview
Here are some of the most familiar images in the western world. I have improved them, though sacrilege as it may be to some. The adjusted images provide a better-quality experience for persons with:
Color blindness
Blocked visual fields (caused by conditions such as macular degeneration, glaucoma, and diabetic retinopathy)
Photophobia (largely associated with migraine conditions) whom often filter images to grayscale using accessibility tools.
The adjusted images will also hold up better in various environments and production methods, including:
Low light
Glare
The CMYK printing process
Grant Wood
American Gothic: Improved color contrast between the characters and the background and higher saturation for the clothing.

Note: Color should never be the primary differentiator. Moving the letters directly under the bars, made them primary and the colors secondary.

Environmental Impact
Road signage, in particular, has the aditional burden of needing to function within a wide range of natural habitats.

Color Block Swimwear: Improved hue and value contrast to maintain vibrant color for color-blind persons.

Emotional Color
Color wheels that assign specific emotions to colors are common and somewhat based on research. How does emotional color work for color-blind persons? The short slide deck below studies that question.
I-See-U Color Scheme Studies
Do the the I-See-U color schemes work in practice? The short slide deck below studies that question.
