I used to make all my ambigrams in simple black and white. However, lately I have been adding colour and decorations to some of the designs and I'm quite happy with that. This was partially due to the latest ACAC, which specifically encouraged holiday themed decorations. So far I've kept things relatively simple. The following ambigram takes the colours and decorative elements a step further though.
Designing the lettering was a lot of fun. The chain solution allowed for some easy letter conversions, so I had a lot of freedom styling the letters. From the psychedelic theme came the idea to give the letters all these weird organic and fractal like ornaments. Naturally all the colours had to be very bright and contrasting to make the experience complete.
The process behind this work was also different in that I used Inkscape besides GIMP. I do really like the way GIMP handles paths and how it can work with both vectors and pixels. Yet this time I had to fiddle with a lot of different shapes and layers, which I felt were managed more easily with a real vector editor like Inkscape.
