Choosing the right colors for your Website is a complex and often daunting task.
Many companies hire independent, special consultants just to devise color schemes that support and enhance an overall brand. However, if you have a sense of color harmony and understand the responses that certain colors can evoke, you can be your own color consultant and develop highly effective color combinations. Before you begin mixing and matching colors, you must first have a firm understanding of your site's message and goals. Once you understand what message you want to communicate, remember that perfecting a color palette is an iterative process, and above all, a creative one. Don't be afraid to experiment with surprising color combinations, but be sure to adequately test the results before unveiling your product to the public.
Color tips and guidelines
Understand your site's message and brand. Choose colors that reinforce your message. For instance, if designing a site for a financial institution hoping to convey stability, choose cool, muted colors such as blue, gray, and green. In this case, using warm, vibrant hues would undermine the site's brand.
Understand your audience. Cultural differences can lead to unexpected responses to color. Additionally, demographic segments and age groups respond to colors differently. Younger audiences generally respond to more saturated hues that are less effective with older segments.
Use a small number of colors in your palette. Four or five colors, in addition to white and black, should be sufficient. Too many colors create discord and distract the user.
Use contrast for readability. Colors similar in value do not provide enough contrast and hinder legibility. Black text on white backgrounds provides the highest degree of contrast.
Use grayscale to test contrast. When dealing with hues other than black, white, and gray, it's sometimes difficult to determine the relative value of each color. To ensure that your color palette provides enough contrast, create a wireframe mockup and convert it to grayscale.
Be aware of timeliness when choosing colors. Color trends can quickly saturate the marketplace, and consumers rapidly become numb to fashionable hues. On the other hand, you can use popular color palettes from decades past to evoke feelings of nostalgia.
Consider functional colors when choosing a palette. Don't forget to establish functional colors for elements that communicate contextual information, such as headings and links.
Prepare for color differences on the Web. Every Web developer knows that even Web-safe colors appear differently across platforms. Be sure to correct for gamma differences and test your color palette on multiple platforms.
