An RGB color value represents RED, GREEN, and BLUE light sources. An RGBA color value is an extension of RGB with an Alpha channel (opacity). RGB Color ValuesIn HTML, a color can be specified as an RGB value, using this formula: rgb(red, green, blue) Each parameter (red, green, and blue) defines the intensity of the color with a value between 0 and 255. This means that there are 256 x 256 x 256 = 16777216 possible colors! For example, rgb(255, 0, 0) is displayed as red, because red is set to its highest value (255), and the other two (green and blue) are set to 0. Another example, rgb(0, 255, 0) is displayed as green, because green is set to its highest value (255), and the other two (red and blue) are set to 0. To display black, set all color parameters to 0, like this: rgb(0, 0, 0). To display white, set all color parameters to 255, like this: rgb(255, 255, 255). Experiment by mixing the RGB values below: |
