It's called "Lemongrass" from Behr. It's a very startling bright green when in the paint-pot, but dries to a (slightly) more subtle, new-leaf-new-grass green.
It's one one wall only: the rest of the room is Lunar Light.
Rainy weekends mean that more painting has been done. Dylan finished the painting in the living room for me. So now we have about half the house painted... still a lot to do. And I really must get around to putting in skirting/baseboards.
