  3. Color gradient - Wikipedia

    en.wikipedia.org/wiki/Color_gradient

    An axial color gradient, with a white line segment connecting the two points. An axial color gradient (sometimes also called a linear color gradient) is specified by two points, and a color at each point. The colors along the line through those points are calculated using linear interpolation, then extended perpendicular to that line.

  4. Dither - Wikipedia

    en.wikipedia.org/wiki/Dither

    The 256 available colors would be used to generate a dithered approximation of the original image. Without dithering, the colors in the original image would be quantized to the closest available color, resulting in a displayed image that is a poor representation of the original. The very earliest uses were to reduce images to 1-bit black and white.

  5. Image gradient - Wikipedia

    en.wikipedia.org/wiki/Image_gradient

    The gradient of the image is one of the fundamental building blocks in image processing. For example, the Canny edge detector uses image gradient for edge detection. In graphics software for digital image editing, the term gradient or color gradient is also used for a gradual blend of color which can be considered as an even gradation from low ...

The CS4 icon is almost identical, except for a slight alteration to the font and the color which is dark gray.

  8. RGBA color model - Wikipedia

    en.wikipedia.org/wiki/RGBA_color_model

    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.
