Screen layers can be helpful in graphic design and in creating multiple exposures in photography. Leonardo da Vinci's Vitruvian Man overlaid a soft light layer Moses Harris's Color Wheel and a soft light layer of Ignaz Schiffermüller's Color Wheel. Soft light layers have a darker, more translucent look than screen layers.
The oil painting becomes more transparent with age, so to avoid a gradual brightening of the picture, a pale beige color of ground is considered neutral. [4] White ground provides the greatest freedom of choice for colors, while colored grounds reduce the color range and force the use of more opaque paint application. [1]
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]
One color entry in a single GIF or PNG image's palette can be defined as "transparent" rather than an actual color. This means that when the decoder encounters a pixel with this value, it is rendered in the background color of the part of the screen where the image is placed, also if this varies pixel-by-pixel as in the case of a background image.
Ultramarine is a deep blue color pigment which was originally made by grinding lapis lazuli into a powder. [2] Its lengthy grinding and washing process makes the natural pigment quite valuable—roughly ten times more expensive than the stone it comes from and as expensive as gold.
In interior design, a wash or color wash of paint on a wall can be used to create a textured effect as a faux finish. [2] In ceramics, a wash is typically a coloring oxide thinned with water applied to the piece to achieve an effect similar to a glaze. [3] Digital image creation software can have features that simulate the painting technique. [4]

In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.
