Light and Darkness in UI Design. Matter of Choice

The article is about the basic aspects of choosing an efficient color scheme and balance of light in the darkness, enhancing the usability of the user interface.

In one of our previous articles, we have already mentioned that the issue of color is one of the major in the design of user interfaces. It can greatly influence the level of usability as well as the attractiveness of a mobile application or website. And one of the first questions designers usually have to answer is what kind of general color scheme to choose: should it be dark-on-light or light-on-dark?

Here we are going to consider some points of importance in this significant stage of UI design.

Aspects affecting the choice

Lots of discussions are raised here and there about the color scheme, which is more effective in creating good interfaces. Although lots of participants in this big debate try to find a universal solution, here in Tubik Studio, we suppose the cure-all does not exist. Every project in UI/UX design is highly individual and needs a thoughtful approach weighing all pros and cons.

There are several vital aspects that should be taken into account in the initial stages of choosing the general color scheme for a website or application.


This aspect should include the ability of the user to clearly see and distinguish all the necessary details on the screen or page. The color scheme and combinations should support easy and intuitive navigation and make the most functional elements of the layout stand out effectively. When this aspect is not considered or not tested properly, it can bring to the products which make a complete mess on the screen in which users do not see what they really should. One of the ways to check it is the widely used “blur effect” when you look at the screen or page in the blurred mode and check if everything vital is easily and quickly observed.


The choice of background for the screen usually influences the level of readability – the ability of users to read text easily. This aspect should be considered among the first, especially if an app or a website is text-driven. Poor readability level is the main reason why users miss important data or feel inexplicable tense using the product as all the way they have to struggle with the text, which takes considerable effort to read. No need to say that the lack of readability can be a serious reason why users are not retained even with attractive products.


In the sphere of UI/UX design, accessibility is mostly defined as the ability of the product to reach as many people as possible. That means that the decision “to use or not to use” should be mostly based on the user’s needs and wishes but not on their physical abilities. Color scheme issue is among the main factors affecting this aspect. Taking it into account, a designer should think over the users of different ages, special needs, and disabilities, which can also determine the choice of color for the background and layout elements.


Designing app screens or web pages, it is also important to remember that users are going to use the product on different devices. That can have a crucial effect on usability as often what looks slickly stylish, attractive, and clear on a high-resolution professional monitor can transform into a dirty stain on the small low-res screen. In every project, designers should take their time to check their solutions on different devices and in various resolutions: that simple step enables them to reveal the problems and fix them in the early stages of design. Color scheme certainly, influences this issue.


One more thing to consider while choosing the appropriate color scheme and the type of background is the potential environments in which users are going to use it regularly and frequently. In terms of constant use under natural light, the dark background can literally create the effect of reflection, especially on glossy screens typical for tablets and smartphones. On the contrary, in terms of regular use in a badly-lit environment, the dark background can take the light away from the screen, which has a bad influence on navigation and readability. So, the issue of color combinations, contrast, and shades draws big attention here.

Therefore, as we can see, choosing the appropriate background color for the layout is a vital step affecting such a key characteristic of any product as usability.

Steps to follow in choosing the color scheme

Here is the short checklist of basic things to follow, making solutions on the general color scheme.

Clearly define the aim of the product

It is very important to define the most important useful points of the product which are going to solve the user’s problems. This data will determine what kind of content drives your product.

If it is text-driven stuff like a blog app or e-reader, for example, perhaps light background will be a better choice. The light will create the feeling of a more airy and spacious screen or page, and it will be easier to concentrate purely on the text.

However, if your product is visually driven and moves more round images rather than text, a color scheme with a dark or bright background for the interface can become an efficient solution as the colors of the images can feel deeper, and the general layout, if accomplished properly, can get stylish and sometimes even luxury look.

Analyze your target audience

As we have mentioned plenty of times in our previous articles, defining and analyzing the target audience is the first thing a designer should do to work on effective design solutions. Knowing who is your potential user and what they will want to get from your product is the solid basis for a helpful, usable, and attractive interface. Middle-aged and older people tend to like interfaces with light backgrounds as they find them more intuitive and navigable. Younger people can find well-performed interfaces with the dark background more original and stylish, and it can be a way to involve target users. Teenagers and children can be attracted to thought-out interfaces using bright backgrounds and funny details. Certainly, it deeply depends on the nature of the product functionality and content; however, typical preferences of the target audience can also be a good clue to efficient decisions.

Research the competition

One more thing to remember is that your product is not going to appear one and the only on the market. It is going to participate in great and dynamic competition, the prize in which is popularity and users’ attention. The choice of color scheme can be the way to make a product stand out from the crowd, which can be crucial to enable the first wish of interaction from the user’s side. Time spent on researching the existing products in the sphere can save much more time and effort on the redesign of ineffective solutions.

Test as much as possible

All the aspects mentioned above should really persuade in one key thing to do: as the color is perhaps the most important tool affecting the level of usability and attractiveness of the product, every design solution should be tested properly, in different resolutions, on different screens, and under different conditions. Testing proves the strong and weak sides of your choice before the product goes out on the market, gets discussed, and loses the chance of a stunning first impression in case of inefficient design solutions.

In practice, we have published earlier two practical case studies on UI design in which color schemes were redesigned in the process. In the case of the Echo App design, it was made after the problems revealed via user testing, while in the case of the Tracking App, it was determined by the issue of consistency for all the versions of the product. Welcome to read the cases in detail.
