Query or Change Dynamic Colors (OSC 10–19)

When n is between 10 and 19 inclusive, either query or change the dynamic color corresponding to n depending on the value of c. c may be provided multiple times, each separated with a semicolon (;).

If c is given as a single character ?, then the terminal will respond with the color specification of the dynamic color at index n. If c is a valid color specification, then the dynamic color is changed according to it.

If there are more cs left in the sequence, then n is incremented by one, and the process repeats.

The correspondence between n and the dynamic colors are as follows:

n	Color
10	Foreground color
11	Background color
12	Cursor color
13	Pointer foreground color
14	Pointer background color
15	Tektronix foreground color
16	Tektronix background color
17	Highlight background color
18	Tektronix cursor color
19	Highlight foreground color

Note

Currently, Ghostty only supports n between 10 and 12 inclusive. All other dynamic colors are ignored.

As an example, this sequence changes the background color and the cursor color to red and blue respectively:

This is equivalent to combining an OSC 11 and an OSC 12 together:
