what is the color depth of a deep color photo
Color depth Deep color consists of a billion or more colors,[14] 230 is 1.073 billion. Color depths of 30, 36, and 48 bits per pixel are in use, also referred to as 10, 12, or 16 bits per RGB channel/sample/component. Often an alpha channel of the same size is added, resulting in 40, 48, or 64 bits used for each pixel.
Pixel The number of distinct colors that can be represented by a pixel depends on the number of bits per pixel (bpp). A 1 bpp image uses 1-bit for each pixel, so each pixel can be either on or off. Each additional bit doubles the number of colors available, so a 2 bpp image can have 4 colors, and a 3 bpp image can have 8 colors:
Paint Pigments are granular solids incorporated in the paint to contribute color. Fillers are granular solids incorporate to impart toughness, texture, give the paint special properties,[13] or to reduce the cost of the paint. Alternatively, some paints contain dyes instead of or in combination with pigments.
Indigo Indigo is a deep and rich color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between purple and blue; however, sources differ as to its actual position in the electromagnetic spectrum.
