The color scheme is mentioned among the top factors affecting this aspect. So, the decision “to use or not to use” has to be mostly grounded in users’ needs and preferences, not on their physical abilities. So, based on this, if the interface presents a lot of copy and suggests a long-reading experience, a light background may feel more user-friendly.Īccessibility is mostly defined as the ability of the web or mobile interface to reach as many people as possible and provide its functionality regardless of any discriminations. With a dark display (black background) the iris opens to receive more light and the deformation of the lens creates a much fuzzier focus at the eye. With a bright display (white background) the iris closes a bit more, decreasing the effect of the “deformed” lens. Part of this has to do with light levels. People with astigmatism (which according to various stats present about 50% of the population) feel it harder to perceive white text on black than black text on white. Why may that be so? Jason Harrison from Sensory Perception and Interaction Research Group (University of British Columbia) explains this phenomenon in the following way. In particular, they found that participants were 26% more accurate in reading text when it was featured with dark characters on a light background. Bauer and C.R.Cavonius shared their explorations in the paper “Improving the legibility of visual display units through contrast reversal” (1980). Studying how advertising carriers worked, D. However, some scientific studies dating back to the 1980s show that for big bulks of text light background appears to be a more effective choice for the majority of users. Legibility suffers much more in color schemes that make the text any lighter than pure black, especially if the background is made any darker than pure white.» So, any color scheme may be readable enough if the designer studies the peculiarities of copy perception on different backgrounds and works carefully on the font choice. Although the contrast ratio is the same as for positive text, the inverted color scheme throws people off a little and slows their reading slightly. White text on a black background (negative text) is almost as good. Optimal legibility requires black text on white background (so-called positive text). Poor readability results in poor user experience: users aren’t able to scan the data, even more – even if the data is relevant but not readable, users feel the inexplicable tense struggling with the text or may even miss the critical information.ĭoes it mean that interfaces with a light background are more readable? Not always. One of the famous gurus of user experience design Jacob Nielsen mentioned: «Use colors with high contrast between the text and the background. For example, as well as with physical objects perceived on different backgrounds, the black copy shown on white or light background seems to be larger than the white copy on a dark background. Among many other factors, the color scheme chosen for the interface plays a crucial role in the effective process of text perception. These characteristics should be carefully considered, especially for the interfaces filled with a lot of text. Legibility measures how quickly and intuitively users can distinguish the letters in a particular typeface. Readability defines how easily people can read words, phrases, and blocks of copy. These terms are both directly connected to the perception of the content presented with text. Let’s review the essential factors which have to be considered regarding the issue. The solution heavily depends on numerous factors covering not only the user’s side but also business goals, market conditions, and current design trends. Today we are going to discuss one of the frequent choices UI designers have to make project by project: which scheme is better for the interface, light or dark? Factors influencing the choice of color schemeīe sure, there is no one particular choice which would work for all the aims. In both personal and professional life, we have to consider numerous oppositions and challenges, and it’s better when solutions are based on not only suggestions but also facts, experience, and knowledge. Our everyday life is an endless flow of choices.
