Bitcoin developer Entero Positivo launched “BIP39Colors” last month, an open-source tool that can convert one’s BIP39 mnemonic phrase into a series of colors, and vice versa.
“With this method, you can convert your 12-word phrase to 8 colors (or your 24-word phrase to 16 colors),” explained Positivo to Decrypt via DM. “Then you can convert your colors back to your original seed.”
Sounds clever but is not terribly useful. If I’m storing it on a computer it’s going to be encrypted, I would just leave it as a seed phrase. If I wanted to print it out and have a physical copy, this would require a high-fidelity printer, with an equally high-fidelity way to scan the colours to be able to match the exact colour. Then I’d have to hope that the colours don’t fade over time and I’d need the perfect lighting when I do re-capture the colours. Sounds like it simply wouldn’t work.
