# `PgRedValue`, `PgGreenValue`, `PgBlueValue`

`PgRedValue`, `PgGreenValue`, `PgBlueValue` -- indicate color strength.

## Syntax

    PgRedValue(color)
    PgGreenValue(color)
    PgBlueValue(color)

## Arguments

`color`

  A 24-bit color number usually held as a hexadecimal number between 0x000000 (black) and 0xffffff (white).

## Returns

A numeric representation of the red, green, or blue portion of the `color`.

## Description

The return value is a number between 0x00 and 0xff (0-255 decimal) indicating the strength of the blue, red, or green portion of the `color`. In Photon, colors are held as 24-bit numbers. The most common representation of these numbers is a hex number of the form: `0xrrggbb` where `rr` is a hex value of red, `gg` is the hex value of green, and `bb` is the hex value of blue.

## Example

        Gamma> color = PgRGB(77,0,128);
        0x4d0080
        Gamma> PgBlueValue(color);
        0x80
        Gamma> PgRedValue(color);
        0x4d
        Gamma> PgGreenValue(color);
        0x0
