Create solid color PPM images

TLDR

Create solid color image

$ ppmmake [color] [width] [height] > [output.ppm]

Create red image

$ ppmmake red 100 100 > [red.ppm]

Create using RGB values

$ ppmmake "rgb:ff/00/00" 200 200 > [output.ppm]

SYNOPSIS

ppmmake [-maxval val] color width height

ppmmake creates a PPM image of the specified dimensions filled with a single solid color. Colors can be specified by name (red, blue, white), hex notation (#rrggbb), or RGB triplet format (rgb:rr/gg/bb).This is useful for creating background images, test patterns, or blank canvases for compositing with other Netpbm tools. The companion tools pgmmake and pbmmake create grayscale and bitmap images respectively. Part of the Netpbm toolkit.
