I used to play with these, lots o' fun.
Neat, not an integer shell version though. It would be interesting if someone else has actually done it...
Working on Nth root at the moment, but I suspect it will be a step too far for a POSIX shell.

bsetroot
bsetroot(1) General Commands Manual bsetroot(1)
NAME
bsetroot - blackbox utility to change root window appearance
SYNOPSIS
bsetroot -help
bsetroot [ -display display ] -solid color
bsetroot [ -display display ] -mod x y -fg color -bg color
bsetroot [ -display display ] -gradient texture -from color -to color
DESCRIPTION
Bsetroot is a utility that can control the appearance of the root window in three ways: Either give it a solid color, or write a two color
modula pattern to it, or render a gradient texture, based on two different colors.
Bsetroot resembles xsetroot(1) in this functionality but it supports multiple screen displays, and gradient textures the same way as Black-
box does. It doesn't handle cursors etc. Bsetroot is part of the Blackbox package.
OPTIONS
Bsetroot operates in three ways, you must choose one of the first 3 options:
-solid color
Sets the root window to specified color.
-mod x y
Creates a modula pattern. You must specify -bg and -fg colors.
-gradient texturestring
Renders the specified texture string to the root window. For possible texture strings, please refer to blackbox(1). You must also
specify both a -from and a -to color.
-display display
Tells Bsetroot to connect to the specified display.
-bg, -background color
Background color. Needed for -mod patterns.
-fg, -foreground color
Foreground color. Needed for -mod patterns.
-from color
Start color for rendering textures. Needed for -gradient operation mode.
-to color
Ending color for rendering textures. Needed for -gradient operation mode.
-help Prints version info and short help text.
