Inclusive-Color

Color Blindness Simulation for UIColor

This library was demonstrated at the Color Me Surprised! Architecting a Robust Color System in Swift talk presented at try! Swift Tokyo 2017.

What it Does

This library provides a UIColor function that may be used to simulate the appearance of a color as it would appear to a user experiencing the following color limited visual deficiencies and anormalities:

- protanopia
    - A red-green color deficiency specifically hindering the perception of red hues.
- protanomaly
    - A red-green color abnormality specifically hindering the perception of red hues.
- deuteranopia
    - A red-green color deficiency specifically hindering the perception of green hues.
- deuteranomaly
    - A red-green color abnormality specifically hindering the perception of green hues.
- tritanopia
    - A blue-yellow color deficiency.
- tritanomaly
    - A blue-yellow color abnormality.
- achromatopsia
    - A deficiency affecting all hues.
- achromatomaly
    - An abnormality affecting all hues.
- normal
    - No color limitations.

How to Use

Simply call func inclusiveColor(for type: InclusiveColor.BlindnessType) upon a UIColor instance to display the color as it may appear to an affected individual.

Example:

let color = UIColor.red.inclusiveColor(for: .deuteranopia)
