where to paint my tester pots

[KnitThroughTheBackLoop]

We bought a house a few months ago and are living in our flat while we have some work done on it. The builders are telling me its time to choose a paint color so I've ordered some testers from Dulux but I'm not sure where to paint them. We have two small children and it doesn't really work to take them with us to the house at the moment because of all the tools and half finished jobs around the house so the only time it is easy to visit is in the evening (dh one night while I stay here and me the next night). Also there are no lights in the house at the moment (just wires dangling from the ceiling). Can I paint the testers onto some cardboard and look at them here and then take them to the house and try to look at them in various rooms (using evening sunlight?). Would the color be the same on cardboard as it would be on the wall? I could try to go there and paint them on the wall although we are thinking to do the whole house in one color for the moment so I'm not sure which would be the best place to paint? I've read threads on here about how some colors look pink or gray depending on north vs south facing and I'm starting to feel a bit hopeless and that I should just let them paint the whole thing with whatever almost white color they would have picked before I said I wanted to pick.

That really is the best way to do it anyway. Get some nice big bits of cardboard... Say A3 or something, and paint with at least a couple of coats of your testers (card can be very porous, so you might need an extra coat ). That way you can move them from wall to wall, or room to room. You also get the painting out if the way in your own time.

I always paint big squares of different colours on each wall in the room. Those near the window inevitably look different. I then live with the testers until I am sure.
I really don't think cardboard would give the same feel.

For starters big piece of card and stick it to the walls of your existing flat (having worked out which rooms fade the same way as your new house) if your thinking of only one colour that should at least let you rule out colours that make dark corners too dark or that bleach to zzzzing dullness in full sun.

Face, not fade

thanks. I will try several coats on some card and try different positions in the flat first. the builder offered today to paint some bits of tester paint on a wall where the plastering is finished so maybe once I've narrowed it to my top few I'll try that as well.

I tend to paint on to big bits of lining paper, then cut right up to the edge if the paint. (If not the surround buff paper can make the colour look different). I've never been a fan of painting testers on the walks as the texture of the paint strokes can show through when painted over fussy I know
