Maybe it's just my eyes and monitor, but looking at the "Crawford Red" http://www.dcdalgliesh.co.uk/tartan_found.rpy?id=450668 I'm having a hard time discerning the Green (Green10 Yarn) from Black. Even viewing the image at it's largest resolution, examining where the 'green' lines cross, it seems like alternating black and very dark grey... just wondering; maybe that's just the way Green10 is going to appear.
