I know - the colours are not how we are used to see runestones. Just like ancient Roman buildings, statues and pillars are always shown as clean white marble in films, whereas they were actually painted just like their Egyptean counterparts.
It's the heritage of centuries of archaeology without the possibilities of modern spektral analysis and stuff like that.

But imagine - the past was MUCH more colourful and bright than we thought when we grew up

I was reading Bernard Cornwell's novels about Uthred of Bebbanburg over a couple of seasons, and I'm still resisting the urge to dive into yet another new big project/period....
