Colors

Computers can also use hexadecimal. I will explain the system and also the color uses of hexadecimal. As well as RGB and CMYK.

For computers to have color they need hexadecimal. Hexadecimal is a number system using 16 symbols. {0123456789ABCDEF}
This also means the place values will add 16 every place value. The first three places would be
{32 16 0}

So you would just count until 9 then ten is represented by A. 11 is B. 12 is C. 13 is D. 14 is E. 15 is F. Then once you get to F you would start over with 0 but with a 1 in the 16s place.

To make color on the computer there needs to be six hexadecimal digits. The digits are divided by three colors. Red Green and Blue.

The first two digits in the # are representing Red. The second two digits are for blue. And the last two are for green.

The max amount of color that can be made is FF. For example if the computer wants to make the fullest color of green the hexadecimal number would be #00FF00.

(There is always a # sign in front of the number to show it is a hexadecimal number.)

You can have other colors than just Red Green and Blue if you just have different amounts of two colors at the same time.

For example red and blue make purple. If we have #FF00FF then that would make the fullest color of purple. Kinda.

The lower the numbers are then lighter the color will be.
#000000 = black
#FFFFFF = white

RGB stands for Red Green Blur and is used for electronic color. It is similar to hexadecimal however it doesn't use letters. Instead it just uses numbers 0-225.
225 is the same as FF.

Each color is separated by commas for example the fullest color of red in RGB mode would be
225,0,0

To make a light purple would be around
(204, 186, 220)

Sometimes it is hard to remember what the middle of FF is so it sometimes is hard to remember what kind of shade it is.

So now you know how hexadecimal colors work.

CMYK is another kind of mode but is used for printing. It's not for computer color just print color.

CMYK stands for Cyan Magenta Yellow and Black.
Just like the other color systems it uses a number in each color value to determine how much of each color to use.
