Understanding Color Deficiencies


Color is an important part of our daily life and can bring a home's design to life. However, individuals with color deficiencies may struggle to distinguish and differentiate between colors in the home's design. Accounting for these differences will ensure everyone is able to appreciate and enjoy the chosen colors.

There are three main classifications of color deficiencies:

Red/green deficiencies: This classification of color deficiency is the most common and affects approximately 8% of males. Individuals with this type of deficiency possess varying degrees of being unable to distinguish between shades of green and red.

Yellow/blue deficiencies: Individuals with yellow/blue deficiencies are unable to distinguish between colors in the yellow/blue spectrum. They are able to successfully differentiate between colors that differ on the red/green confusion lines.

Achromacy: Achromacy is very rare and prevents the individual from being able to distinguish between colors of the same brightness.

Understanding developments in interesting color science can have a significant impact on home design. There are several different ways to account for color deficiencies in design, including:

•Limiting the colors that require discrimination and focusing on a color palette that is easily distinguished.

•Varying the brightness of colors in the design to provide different luminances.

•Focusing the design on neutrals with bright pops of color. Make sure these colors are easily distinguishable by the homeowner.
