You can specify either a name, such as OliveDrab, or a hex value, such as #6b8e23 or #7fffd420. A Cascading Style Sheet (CSS) color definition. The list of possible enumeration values appears at the end of this topic. A Cascading Style Sheet (CSS) color name. If you specify a Color enumeration value or you build a ColorValue formula with a color name or a 6-digit hexadecimal value, the alpha setting is 100%, which is fully opaque. For example, this diagram shows how the three primary colors mix with an alpha setting of 50%: As a result, colors will blend through the layers. In a canvas app, you can layer controls in front of one another and specify the transparency of a control to any controls that are behind it. The amount of fade varies from -1 (which fully darkens a color to black) to 0 (which doesn't affect the color) to 1 (which fully brightens a color to white). The ColorFade function returns a brighter or darker version of a color. An alpha channel varies from 0 or 0% (which is fully transparent and invisible) to 1 or 100% (which is fully opaque and completely blocks out any layers behind a control).
The function also includes an alpha channel for mixing colors of controls that are layered in front of one another. The RGBA function returns a color based on red, green, and blue components. The alpha channel is represented by aa: 00 represents fully transparent, and ff represents fully opaque. The string is in the format "# rrggbbaa" where rr, gg, and bb are identical to the 6-digit form.
CSS color name: "RoxyBrown" and "OliveDrab" are examples.
The ColorValue function returns a color based on a color string in a CSS. You can find a list of these colors at the end of this topic. Descriptionīy using the Color enumeration, you can easily access the colors that are defined by HTML's Cascading Style Sheets (CSS). HEX is a color represented by a 6-digit hexadecimal value starting with "#".Use built-in color values, define custom colors, and use the alpha channel. It is one of the most widely used color systems. These two representations attempt to be more intuitive than the geometric structure of RGB based on a Cartesian coordinate system. HSL is a representation of the points in the RGB color model in a cylindrical coordinate system. The name alpha was derived from the Greek letter used in the classical linear interpolation equation alphaA + (1-alpha)B.ĪRGB is a color mode, which is the RGB color mode with an Alpha (transparency) channel attached to it, commonly used in 32-bit bitmap storage structures. The colors used are RGB, which can belong to any of the RGB color spaces, but Catmull and Smith proposed this indispensable alpha value between 19, making alpha rendering and alpha synthesis possible. Although it is sometimes described as a color space, it is really just the RGB model with additional information attached. RGBA is the color space representing Red (red) Green (green) Blue (blue) and Alpha. RGB is the color representing the three channels of red, green and blue, and this standard includes almost all the colors that human eyesight can perceive, and is one of the most widely used color systems. RGB color mode is a color standard in industry, which is used to obtain various colors by changing the three color channels of red (R), green (G) and blue (B) and superimposing them on each other. This tool can provide color conversions between the following formats:
