We've had a colouring tutorial period over at Scrapptorget, and if your Swedish is ok you can check out my Copics tutorial and the other tutorials in Scrapptorget's blog.
There are tutorials on how to colour with Distress Markers, watercolour pencils, Inktense, ProMarkers, etc. - and there's also a very good tutorial on how to mask your stamps and make a gorgeous background (something I will try as soon as I have the opportunity)! :)
Hopefully you can find something useful - even though you're not fluent in Swedish ;) - and there are lots of pictures to look at.
The stamp I coloured with Copics was this:
In a couple of days I'll show you a card I made with this coloured motif. :)
