However, blue appears dark
on white, but luminescent on black.
The human condition also adds a further wrench in the works. Many colors have cultural
significance, whether from language (cowardly yellow) or advertising and branding. One
person may consider a color one thing (green equals fresh), and another may have different
ideas entirely (green equals moldy). There??™s also the problem of color blindness, which
affects a significant (although primarily male) portion of the population, meaning you
should never rely entirely on color to get a message across. Ultimately, stick to the following
rules, and you??™ll likely have some luck when working on color schemes:
Work with a color wheel, and be mindful of how different schemes work.
Use tints and shades of a hue, but generally avoid entirely monochromatic
schemes??”inject an adjacent color for added interest.
Create contrast by adding a complementary color.
Keep saturation levels and value levels the same throughout the scheme (a color??™s
value increases the closer it is to white).
Keep things simple??”using too many colors results in garish schemes.
Don??™t rely on color to get a message across??”if in doubt about the effects of color
blindness, test your design with a color blindness simulator application such as
Color Oracle (http://colororacle.cartography.ch/).
Go with your gut reaction??”feelings play an important part when creating color
schemes. What feels right is often a good starting point.
