Colour banding is a problem of inaccurate colour presentation in computer graphics. In 24-bit colour modes, 8 bits per channel is usually considered sufficient to render images in Rec. 709 or sRGB. However, in some cases there is a risk of producing abrupt changes between shades of the same colour. For instance, displaying natural gradients (like sunsets, dawns or clear blue skies) can show minor banding.
Colour banding is more noticeable with fewer bits per pixel (BPP) at 16–256 colours (4–8 BPP), where not every shade can be shown without dithering
Possible solutions include the introduction of dithering and increasing the number of bits per colour channel.
Another solution includes using a Gaussian blur, which removes bands between colour levels in colour banding.
