Color Picker

Here when this "Only Web Colors" box is checked, the color picker window would give you only the safe web colors.

With the New and Current box, this would give you the current foreground or background color and the new color that your cursor has picked now.

Hue: It is a degree between 0" and 360" that measures the reflected color.

Saturation: It is a percentage that measures the strength of the color.

Brightness: It is a percentage that measures the lightness or darkness of the color.

The RGB counters measure the number of each color, Red, Green, and Blue.

The LAB colors counters measure the color with numbers that you can enter in the boxes.

The CMYK colors are also determined by numbers of each counter that you can enter to get the color that you want.

Tip: The difference between RGB and CMYK colors is that the RGB is used for web generated images, while CMYK is used for printing purposes.

The "Add to Swatches" button would add the color that you picked to the swatches palette.

This button would switch you to another view of the color picker which is "The color Libraries"

Each color has it's own digits that might contain letters and number, so you can enter the color code here.
