My First Honeycomb design using GMIC

Showcase
1

For a very long time I wanted to create this design in GIMP, but I didn’t know how to write a script either in Script-Fu or GMIC. Almost after a decade I gave another shot with some help from AI, I figured out how to create one.

Heartfelt thanks for the creators of GMIC and the community, appreciate it very much.

GMIC script:

#@gui _<b>Rajasegar</b>
#@gui Hexagon Grid : fx_hexagon_grid, fx_hexagon_grid
#@gui : Hexagon Radius = int(60,10,200)
#@gui : Color mode = choice("Random", "Patterned")
# Urban Garden color palette
#@gui : Color 1 = ~color(9,70,72)
#@gui : Color 2 = ~color(5,99,98)
#@gui : Color 3 = ~color(75,132,75)
#@gui : Color 4 = ~color(180,178,54)
#@gui : Color 5 = ~color(220,226,192)
