Below are various "middle" grays as based on various criteria.
 
<onlyinclude><includeonly><div style="display:none>"><ref group{{=}}"note" name{{=}}"calibration"><span style="display:none""></includeonly></span>The shades in the rightmost column will only be correct if viewed on a calibrated monitor. View the checked image in the center of the color field for 50% Luminance; if it does not appear to be of the same brightness as the surrounding field, then the "middle grays" rendered in the table are not correctly displayed on your screen.
 
Note that 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 gray field appears to dissolve into the background. Best results if browser window is not zoomed; magnification on outdated browsers 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%.<includeonly></ref></div></includeonly>
