It's better to make your background color darker and less saturated. Darkening the brightness decreases the white in it while desaturating it increases the gray in it. This tempers the color intensity it has on the eyes.
The main reason behind is that a dark background is more comfortable for the audience. Light backgrounds – especially white – release a fair amount of light that can be uncomfortable for the eyes. This is especially true when you present in darkened rooms, typical of TEDx events and seminars.
Neutral colors like white, grey, or beige are popular choices for portrait backgrounds, as they help focus attention on the subject without distraction.
Black backgrounds are effective, and powerful. Black absorbs all light, so it's a low-energy color. It helps to give a lot of “white space” without a blinding glare on large screens. This is especially important in large public presentations using 300' screens.
Using dark mode is helpful in that it's easier on the eyes than a stark, bright white screen. However, using a dark screen requires your pupils to dilate which can make it harder to focus on the screen.
Tan, cream, white, and neutral shades of almost any color on the color wheel can be used. Black and white photographic backdrops also help you achieve a sleek, professional look that highlights your subject perfectly.
Black backgrounds
Not only has it always attracted attention at first glance because it has the darkest shades among colors, but it also highlights the product making every detail highly visible.
Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect. -Easier to read.
When it comes to visual-acuity tasks and proofreading tasks, studies have shown that people with normal and corrected vision perform better with Light mode. This means that text in Light mode is clearer and quicker to understand for people with normal or corrected vision.
Reduces eye strain at night and cuts glare
Dark mode users find reading easier in low light with less eye strain. They also claim it helps them fall asleep quickly and stay asleep longer. This could be because screens expose you to more blue light at night, which could disrupt your circadian rhythm.
Avoid using pure black
Instead, use a dark grey colour for your background, Googles material design guidelines recommend using the colour #121212. Dark grey allows you to use black for shadows so you can keep a sense of depth and has a reduced contrast between itself and white text which will reduce eye strain.
The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
White has 100% color brightness, and black has 0% color brightness. Such a disparity in color brightness creates intense light levels that overstimulate the eyes when reading text. This causes the eyes to work harder to adapt to the brightness.
The general rule of thumb is that skin with cool undertones look best with greys, browns, blues, greens and purples. Skin with warm undertones look best with either bright or light colors. And skin with neutral undertones looks great in bold, bright colors.
The idea behind Dark Mode is that it reduces the light emitted by device screens while maintaining the minimum colour contrast ratios required for readability. Thus reducing the strain experienced by human eyes while extending our smartphone battery.
Light-eyed people (with blue or green eyes) have slightly better night vision because they have less pigment in the iris, which which leaves the iris more translucent and lets more light into the eye.
The warm light of 2,500 to 3,000 K will help you relax while reading and rest better after that. The natural light of 4,900 to 6,500 K is the best solution for eyes that allows comfortable work. The cold light of 6,500 K offers an excellent level of brightness and improves overall attention.
Cons: Dark themes are not always better for eye strain. In bright light conditions, the text appears washed out, increasing eye fatigue. Long pieces of content or text are more challenging to read in this mode.
Studies reveal that red is the most attractive colour to both men and women but, curiously, the two genders are attracted to the same colour for different reasons.
Red is the color of power. It gets people's attention and holds it. It is the most popular color for marketing. The color red tends to increase the heart rate and create a sense of urgency.
Blue, of course. Blue connotes competence, trustworthiness, likability, and calm. As stated above, shoppers were attracted to blue-themed storefronts. You might want to wear blue, especially navy, the next time you want to appear trustworthy and likable.
Blush. The most flattering shades for everyone are colors that are neutral like millennial pink, or blush. Not only does it flatter all skin tones, but it gives you that #glow no matter who you are and pairs well with everything!
As for the least preferred colors, yellow is mentioned in eight studies, while orange and green-yellow are mentioned in five studies each. Thus, the most attractive color is blue, the second most preferred is red, followed by green, while yellow was found to be the least preferred color (Figure 1).
