coloring titanium - red

[slon]

Hello,
I want to ask, how to make red color during anodizing? I can't preparint it, other colors aren't problem.
Thanks

Slon, colors come out in titanium anodizing due to change in the crystalline structure at different voltages. Different voltages cause different structures which results in a different color of light to be reflected and, therefore, seen and interpreted by your brain. Unfortunately, because of this, you cannot achieve a true red color by anodizing titanium. It just won't restructure itself to reflect a true red color. It frustrates a lot of folks!

Chiro75, anodizing DON'T change crystal structure, at the surface rise titanium dioxide and the colors originates in consequence of interferency of light (the same effect as the compact discs).
But how I prepare something look like the red?

Use the search function, this has been disscussed in detail before. I belive the general concensus was that a true red over the entire piece was next to impossible.
