Chart of computer web color grays
Below is a chart showing the computer web color grays. An achromatic gray is a gray color in which the red, green, and blue codes are exactly equal. The web colors gray, gainsboro, light gray, dark gray, and dim gray are all achromatic colors. A chromatic gray is a gray color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade of gray.

White and black
The colors white and black are not usually thought of as shades of gray, but they can be thought of as shades of achromatic gray, as both contain equal amounts of red, blue and green. White is at the extreme upper end of the achromatic value scale and black is at the extreme lower end of the achromatic value scale, with all the colors normally considered tones of achromatic gray colors in between. Since achromatic colors have no hue, the hue code (h code) is left blank for achromatic colors (usually marked as a dash).

White is a color, the perception of which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness. White is the lightest possible color.

Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Black is the darkest possible color. While this platonic ideal black is never found with actual pigments or other coloring, sufficiently dark items are generally referred to as "black".
Achromatic grays
Achromatic grays are colors in which the RGB (red, green, and blue) values are exactly equal. Since achromatic grays have no hue, the hue code (the h in the hsv values of the color) is indicated with a dash. Achromatic grays are the axis of the color sphere, with white at the north pole and black at the south pole of the color sphere. The various tones of achromatic gray are along the axis of the color sphere from white at the top of the axis to black at the bottom of the axis.

Note
- LCD screens, even when correctly calibrated, often have a brightness that varies considerably depending on the viewing angle. Try stepping back and changing your position until the checkered image in the center of the absolute middle gray (50% relative whiteness) appears to dissolve into the background. If the image does not appear to be of the same brightness, then the "middle grays" rendered in the table are NOT correctly displayed on your screen. (Also take care to make sure your browser window is not zoomed since any magnification may distort the brightness depending on how your browser adjusts for gamma when blending the pixels, e.g. rendering the zoomed image at sRGB middle gray, or 21% whiteness, instead of 50%.).
