Aloha O-community. As some of you know, I've recently been getting into anodizing. At first I couldn't understand why I couldn't find a large chart showing all the voltages, similar to what I did here. But now I understand that it's because some of the colors are just too similar. Like the all the 30 volt colors. Or just ugly, because it is in between two other colors. At least you can see for yourself now. These are all polished titanium plates. Not a super shine, but would rate at 7-8/10 shine. So colors may appear a little lighter than what you see if anodizing a pair with a awesome shine. I stopped at 90 volts because that is all my power supply will do consistently. I reached 91 volts with one piece, with that took forever.

Interesting that it sort of repeats, but gets more intense the second go-around.

It's the same chart. I don't have a room with awesome lighting. So I took pictures of the plates at different angles to try and catch some of the shine. That helps to highlight the color progression.

I meant it goes gold, purple, green, and then around 45v for the second half of the chart, it sort of does it again.

Sorry. Yes it does repeat, and I love those second half too. They are different (brighter IMO) from the earlier colors. And sorry about the confusion concerning the amount of photos. There's only one chart and only one plate for each volt. I was using multiple photos with different lighting angles to try highlight each color as much as can. I'm an electrician with bad lighting. Lol.
