Tangent: SRE was very color-heavy and that led to some long ANSI sequences. From the recently decompiled source [1] you can see that I tried to pick shorter ANSI sequences when I could. In particular, going from color 0x0* to 0x1* we could save 1 byte, and going back to the default white on black we could save between 1 and 4 bytes. But if you're bandwidth limited there's also an option to turn off color entirely.
