[pdf-lib](../index.md) › [RGB](rgb.md)

Red, Green and Blue. Each color consists of 8 bits (1 byte) having a
value which goes from 0 to 255. Therefore pdf-lib expresses colors as
fractional values between 0 and 1. You can divide each of your color
component values by 255 to produce the correct fractional value. For
example:

```
rgb(0 / 255, 74 / 255, 153 / 255)
```
