# Inside coloring mode

**Syntax**:(incoloring integer)

Areas inside the set are usually filled in black, but this is only a convention; you could color them in differently to make the fractal look more interesting. The only method available to make areas inside the set visible is to display the value of the latest orbit as the value of each pixel.

The *tutorial on incoloring* has more information and
examples.

XaoS has many different ways to show that value. The cryptic names of the modes
are mathematical formulae, where **real** means the real part of the
latest orbit, and **imag** means the imaginary part. **zmag**
uses the magnitude of the value. The **Decomposition-like** method uses
the angle of the orbit. Also, truecolor incoloring modes are available, that
display one value in each of the red, blue and green color planes (or, for some
modes, in each of the hue, saturation and value planes).

In the scripting language, the incoloring mode is specified by one of the following integers:

- 0

*0* (default)

- 1

*zmag*

- 2

Decomposition-like

- 3

*real/imag*

- 4

*abs(abs©-abs®)*

- 5

*cos(mag)*

- 6

*mag*cos(real^2)*

- 7

*sin(real^2-imag^2)*

- 8

*atan(real*imag*creal*cimag)*

- 9

squares

- 10
