The algorithm.

  1. Create 3-channel image, which is interpreted as HSV image.

    1. 1st channel is the matrix, each element equals hue = 19.
    2. 2nd channel is the matrix, each element equals saturation = 78.
    3. 3rd channel is the matrix of brightness (src + value = src + 20).

  2. Convert resulting image to BGR format.
