This set of colors are intended to get your display
rendering things accurately.
There are the 3 primary colors Red,
Green, and Blue on the right hand side, at the top.
There are precisely 50/50 blends of the primary
colors, for Yellow (Red & Green), Cyan (Blue & Green), and Purple
(Red & Blue).
There is a pure Black, an Pure White, and a pure
Grey (50/50 Black & White).
The Color adjustment, adjusts how much color is
displayed, not what the colors are.
Tint or Hue adjusts what the actual
Brightness adjusts Black.. It controls whether black displays as
black or grey. It also effects overall perceived brightness of the
Contrast adjusts White. Contrast adjusts whether white is displayed as
white or grey.
The adjustment procedure is as follows:
First turn Color all the way down, so that the
display is only black and white.
Adjust the brightness up until black
becomes grey, and then back down, until down it is precisely as
black as it gets, but further adjustment makes it no blacker - NOT
all the way down, just to the exact point in which turning it down
further, makes it no blacker.
Adjust the Contrast down, until the
white becomes grey, then back up until it is at precisely the point
at which white gets no whiter - NOT all the way up, just to the
exact point in which turning it up further, makes it no whiter.
At the completion of the brightness and Contrast adjustment, the
grey bar should remain pure grey a 50/50 black and white
Once the brightness and contrast are adjusted
properly, turn the Color all the way up!
Now, adjust the Tint / Hue to have the proper pure
red / green / blue in the primary color bars, and 50/50 red and
green for yellow, 50/50 red and blue for purple, and 50/50 green and
blue for cyan.
Once those are perfect, turn the color back down,
until images are at a normal color level.
Photos of people, or
videos, makes a reasonable source for color level adjustment
Realize that they are not always
perfect, so sample a wide variety, while making this adjustment, set
the level to
be the best over-all.
Grass should not be neon green, and people
should not look like aliens. Everything should look as natural as
