After writing to you yesterday, I was at the painting room of mr Stewart (the celebrated portrait painter) who had first suggested to me the painting a floor green, which he had himself tried with fine effect. he observed that care should be taken to hit the true grass-green, & as he had his pallet & colours in his hand, I asked him to give me a specimen of the colour, which he instantly mixed up to his mind, and I spread it with a knife on the inclosed paper. be so good therefore as to give it to mr Barry as the model of the colour I wish to have the hall floor painted of. The painters here talk of putting a japan varnish over the painted floor and floor-cloth after the paint is dry, which they say will prevent it’s being sticky & will bear washing. as I have not seen it I cannot say what it is. mr Barry is probably the best judge of it. Accept my good wishes.
