Natural colors are usually uniformly smooth. But even on perfectly even surfaces of the same solid color, natural color transitions form. Always an unintentional fall of sunlight or artificial lighting, as well as a change in the angle of view, gives uneven and unique shades.
Two points of view aimed at the same object perceive its color according to the difference in their viewing angles and the ratio of the angles of incidence of other rays on the surveyed surface.
Psychological effects of color transitions
Color causes not only physical sensations and depends not only on time and position in space. Images of trees, houses, mountains and other objects upside down cause a feeling of reflection in the surface of the water or on another surface.
Absolutely black parallel lines on an ideally white surface of the wall, each straight line along the entire length increases in thickness in proportion to the natural decrease in the line thickness when looking at the wall - all this will cause the viewer to feel that the room has a horizontal ceiling.
One image, on which two are applied, and each of them is offset relative to each other by the distance between the eyes, gives the spatial effect of volume, if you defocus the view.
If the poster is large enough and the boundaries of the transition to reality are perfect, then the image depicted on the poster will be perceived so naturally that the desired shades of color, the mind of the beholder will connect automatically.
The site, and above all, its design and color scheme are important and complement the logic of the resource, its dialogue, produce the proper psychological effect on the visitor.
Smooth transitions through CSS
Gradients are created using the linear-gradient () and radial-gradient () functions. In the first case, a smooth color change occurs along the line, in the second case - along the ellipse or circle. CSS gradient can be set in the background, background-image, border-image, list-style-image properties. By superimposing elements on top of each other, determining their transparency, you can form stunning shades of color and create unique transitions.
However, it should be borne in mind that the color transition may not always be smooth. Some color combinations, transparency values, page background design can produce unwanted, stepwise effects.
CSS background gradient writing rules
Gradient is a smooth transition from one color to another. You can use several colors. Specifying a linear variant (CSS linear gradient) can be varied:
The first parameter is the angle of inclination or the side of the area, then the colors follow. It is not necessary to use only two colors, you can draw the whole rainbow. Using the opacity property of transparency, you can get blending effects.
Color selection, color generators
The creative part of the work of the designer, site developer in recent years has been simplified. Rectangular forms have become practical and expedient, containing a minimum of information, a minimum of functions, a maximum of meaning and a psychological setup to sell a product, provide a service, highlight discounts, quality and / or significant differences from competitors.
However, even in such strict regulations and conditions for creating modern web resources, there is a place for creativity and a clear desire of some developers to do aggressive, targeted work with color, reflecting the meaning of text content and the style of the chosen dialogue. CSS gradient has become more common.
The color schemes of Google and Skype, in particular, had an effect and followers, however, in the last couple of years, the active component of web design began to look for new forms, new color solutions and try unobtrusive dynamics of smooth forms.
A lot of online resources (CSS gradient generator) have appeared on the Internet, which greatly simplify the work on choosing the right colors: angrytools, flatonika, generatecass, etc. With their help, you can save time on choosing the right colors, think over the line of transitions and overlays.
Dynamic color scheme
The traditions underlying the creation of web resources have made the rule unshakable: the structure, content and dialogue of the site with the client is the competence of the developer, realizing the will of the owner (customer). The appearance of the site, its design also traditionally refers to what is not determined by the client.
Meanwhile, the number of various devices is growing, and in the families of each species various perspective copies appear that have significant differences, not so much in color reproduction as in resolution and forms of the visible area of the browser.
The variety of browsers and versions used also creates problems in adequately displaying CSS gradient capabilities.
Taken together, evaluating these circumstances and examples of some promising works, it can be argued that the appearance of the site only in a default state is the competence of the developer and / or resource owner. Only when the client first visits the resource, he can be able to evaluate the design of the site. If the client considered it appropriate to remember the site and use it in his daily life, then his desire to have tools to control the appearance and functionality is quite justified.
Such a transfer of the center of gravity is beneficial to the developer: there is no need to engage in cross-browser implementation, to test the site on various devices in various operating systems.
Moreover, the trend will allow creating a common database on the actual implementation of CSS rules on various devices. This is only the beginning, but its potential is of great importance.
