Shades of green on the trees in May: soft, pale greens, yellow-greens, deep greens and dark green on the evergreens. Up on the mountains subtle gradations of green across the open slopes: bilberry is green tinged with red close-up, but on the far slope the effect is tawny-green interspersed with moss green and vivid grey-green of lichens.
A cuckoo calls to tell us it's Summer but the north wind is chilling up here and the grass is not yet green but bleached white-brown still from Winter.
Heathers between the bilberries are brown-green and gorse is dark green with yellow. All this, looking down the valley from the vantage point of Pen-y-Graig creates a subtle patchwork of soft greens shading to other hues.
Spring and early Summer on the mountains; speckled green.
