A sample in a different setting

Text A: an original contemporary practice extract.

The green paint looked calm on a small card beside the shop window. I took the card home and held it against the wall, then bought a small test pot rather than the large tin I had expected to choose. On a wider patch beside our dark cupboard, the colour seemed stronger than the card had suggested. That was not a trick by the shop; the card had never occupied our room.

I looked at the patch in the morning and again with the lamps on. I chose a different shade for the whole wall and kept the first card while deciding where its colour might suit a smaller surface. The sample had helped me begin a choice. It had not settled what the paint would feel like across a wall among objects the shop did not know I owned.

Text B: an original contemporary practice extract.

The carpet sample lay on the showroom’s pale display table. Its narrow stripes looked almost plain from where I stood. At home, I placed the borrowed square beside the patterned curtains and moved away from it. The stripes became part of a busy arrangement I had not seen in the shop.

I asked to compare a larger sample before ordering. Seeing more of the pattern confirmed that I preferred another design for this room. I still liked the original on its own and could imagine it in a quieter setting. The small square had not been false. It had answered what the material looked like in a limited space, not how my whole room would change when that space became the floor.
