Some websites and online application services allow end user to customize their profiles by uploading pictures, description about them and changing/choosing a background color or a backdrop image as part of personalizing their own space as per their tastes. This is a cool thing a web development company can suggest to their clients and the website developer can implement it during the web design and web development process.

But on the other hand as a web designer or a website developer, this could also be a little scary. This is because giving a few controls of the look and feel of the website in the hands of end user for tweaking layouts could result in the users choosing some weird color combinations. Your entire stock test and images that were designed to work with a nice background will be useless then. Opening up the ability to customize your site’s color scheme can be a recipe for disaster unless you are flexible and understand how to find maximum color contrasts. So a web programmer should limit this to some extend and have a fine balance between keeping the look and feel intact as well as providing options for the end sure to customize it.

A website developer can alternately look at a few pre-made color schemes and corporate colors, which will hold the entire branding and look and feel of the web design as originally planned. And they can also decide whether the text/content should be displayed in black and white, or should also be flexible as per the user’s taste.

The web developer company can suggest some potential background colors and their respective hex values and based on the user preferences the corresponding text can be rendered as white or black. The text color could be purely based on the simple logic in JavaScript at run time. Essentially, this could be based on the higher contrast between white and black - to have the best readability. For this the web programmer can write two simple functions which takes the hex value and compares it to the value halfway between pure black and pure white, and based on this the text can be displayed as white or black.
