We enjoyed a few days of Autumn sunshine last week (wonderful, after a wet, grey Summer!) so one fine afternoon I took my samplers outside where the light was good and took a few photos.
This is a close up of a plain weave section...
My favourite red/orange/yellows:
The two different samplers examined together, same two yarns warp and weft in diagonal twill and in plain weave.
Folding the plain weave sampler enables me to show you, left of picture, the blue-jade yarn warp and weft, centre with a white warp and right with navy blue. Don't you think that the blue-jade colour looks paler with white, and blue against the navy? So much of our perception of colour depends on context. (no, the colours didn't run in the wash!)
Same folding as the above, with the yellow green yarn: left, in warp and weft, centre with white weft and right with navy blue. The reed marks are distinct against navy (you see every group of three warp threads from the 3 per dent reed sleying), but not visible at all on the white.
