If you are new to blogging or website design, color usage on a website can seem a little cryptic at first. This post delves into the very essence of how color works on the web. There are many, many sites with color selectors that discuss the finer points of color and web usage. The point of this post is to give newbies to web colors a strip-down jist of color to jump-start their blog tweaks.
Color basics are …basic, i.e. boiled down to three primary colors: Red, Green and Blue. This color mode is commonly referred to as RGB. RGB colors are the three colors used for electronic formats which coincide with visual color.
Additive Color
RGB colors are additive because the more of each value you add the brighter the color. Red, Green and Blue have a value each from 0 to 255.
| Colors | R | G | B |
| Black | 0 | 0 | 0 |
| Red | 255 | 0 | 0 |
| Green | 0 | 255 | 0 |
| Blue | 0 | 0 | 255 |
| White | 255 | 255 | 255 |
A mix of values create different colors and hues.
| Colors | R | G | B |
| Hot Pink | 255 | 0 | 204 |
| Lime Green | 0 | 204 | 51 |
| Light Blue | 102 | 255 | 204 |
Web colors use Hexadecimal Values
Hexadecimal is just a different numbering system from our common decimal system. Hexadecimal colors follow the range from 0 to 255. Hexadecimal values are from sixteen places: 0 through 9 and A through F. Red, Green and Blue have two hexadecimal digits for each color value.
For Example:
| Colors | R | G | B |
| Black | 00 | 00 | 00 |
| Red | FF | 00 | 00 |
| Green | 00 | FF | 00 |
| Blue | 00 | 00 | FF |
| White | FF | FF | FF |
| Colors | R | G | B |
| Hot Pink | FF | 00 | CC |
| Lime Green | 00 | CC | 33 |
| Light Blue | 66 | FF | CC |
Web colors add a # sign in front of the digits to indicate a color value i.e. #FFFFFF is the web color for white and #000000 is the web color for black.
Color Spectrum
This Color bar fundamentally is made up of the following colors in succession:
#FF0000 #FFFF00 #00FF00 #00FFFF #0000FF #FF00FF
The colors in between these values are gradations or variants.
Websafe Colors?
If you do much research on color usage on the web, "websafe" colors will show-up on some sites. As long as monitors vary as greatly as they do, there really is no such a bird as a websafe color. Primarily, web safe colors are considered primary colors with matching hex values, i.e. #FF00CC as apposed to #F206C3. Using these standard colors is a good idea, but one should not be limited to those color selections in design.
How to Choose Colors
- Find a color scheme from a website and capture the color values.
I don’t advocate cart blanche copying someone else’s design, but you may find a color selection that someone has developed that fits with the direction of your site. One simple way to use those color values is to right-click on the page and view source. - Use an online program. There are a number of good ones. Some of those are:
- Download a free program.
- Use a program installed on your machine. Look through your programs already installed on your machine. Professional programs like Photoshop and Illustrator have extensive color palletes for selection, but you will also find programs like Microsoft Word that have color selectors as well.
