A website is a powerful marketing tool and there are lots to be concerned about rather than just worrying about the images and text. It might represent a company, enterprise or any products. It is equivalent to a personality; just like the faces portray different meanings, website also conveys different meanings with different colors. Though it looks very simple to choose a graphic design, sometimes the design may unintentionally present a defamatory impression; the colors used may convey some unintended meaning.
A web designer plays a very important role in choosing the appropriate colors, design and other aesthetics. So the designers must be aware of the basic concepts behind the color theory. Because, it is the thing that helps them to decide the design, graphics and the appropriate color that goes well with the content.
Here are some basic color theories that would help in web design:
- Relative colors: When a web designer has to decide suitable colors for a site, he can just start up with CSS color function i.e. hsl (). It dissects color into three different parts like hue, saturation and lightness. Hue is expressed in degrees whereas the saturation and lightness are expressed in percentage. Basically hue is expressed as a particular value out of 360. For instance, the hue value of red is 0 and if you want to make it yellow you just have to move the hue to 60. If you want the color to be the exact complement of red, as the value of red is 0, you have to move the hue value to exactly half of 360. This gives 180 and the resulting complementary color will be cyan (180).
- Saturation and lightness: There is no much confusion in saturation and lightness; just by adjusting these values, the designers can make the color look darker or lighter. As the conception of color comes along with hue, it’s definitely easy for the designers to think about the saturation and lightness. Because, once the hue is set, the designer will be having a view of how the website should look like and how dark or light the colors must be.
- Manipulating color with Sass: Basically, Sass (Syntactically Awesome Stylesheets) comprises wide range of color functions; these functions empower you to manipulate several aspects of a color. We can say that Sass is an ideal for the color manipulation techniques that the CSS is lacking. The major functions are saturate, de-saturate, darken, lighten and adjusting the hue. These functions perform a basic mathematics on the original HSL values.
All these techniques can be put into use practically and the themes can easily change the colors. If a client complains about the color, the color can be adjusted in one place or you can also build a single design for multiple sites and make it look different by changing the color scheme.
