RGB to gray

The RGB scale is calibrated so that when a color's three red/green/blue numbers are equal, the color is a shade of gray. E.g. red=50 green=50 blue=50 is gray, without any bias towards red, green, or blue hue.

Why convert RGB to grayscale?

It helps in simplifying algorithms and as well eliminates the complexities related to computational requirements. It makes room for easier learning for those who are new to image processing. This is because grayscale compressors an image to its barest minimum pixel. It enhances easy visualisation.

Does grayscale have RGB?

In fact a `gray' color is one in which the red, green and blue components all have equal intensity in RGB space, and so it is only necessary to specify a single intensity value for each pixel, as opposed to the three intensities needed to specify each pixel in a full color image.

What color is grayscale?

Grayscale is a range of shades of gray without apparent color. The darkest possible shade is black, which is the total absence of transmitted or reflected light. The lightest possible shade is white, the total transmission or reflection of light at all visible wavelength s.
