Choosing colour
How to test a paint colour properly before you commit to it.
A small patch beside the switchboard, judged in a hurry, is how most people choose a colour. It's also how most people end up repainting a room they don't like. A proper test takes a little patience and saves a lot of regret.

How do I test a paint colour before painting my whole home?
Apply sample patches large enough to judge, on more than one wall, and let them dry completely. Look at them in morning light, evening light and under your own lamps, and hold them next to your floor, furniture and curtains. Shade cards and phone screens can't show any of this, so trust the patch on your wall.
Testing Paint Samples on Your Own Wall
Why shade cards and screens mislead
A shade card is printed, not painted, and it's usually a tiny square. Paint has depth and sheen that ink doesn't. A phone or laptop screen is worse, because every screen displays colour a little differently and the brightness setting changes it again. Use cards to shortlist, never to decide.
Make the patch big enough
A patch the size of your palm lets the surrounding wall and light fool your eye. Go larger, a good patch is a sizeable square, so you can step back and see the colour as a surface and not as a spot. Two coats on the patch usually give a truer read than one, since a thin coat lets the old wall show through.
Test on more than one wall
Walls in the same room receive different light. One near the window may look pale and clean, and the wall opposite it may look deeper. Put a patch on at least two walls, ideally one that gets direct light and one that sits in shade, and compare them.
Look at different times of day
A colour that looks lovely at midday can look muddy at dusk. Check the patch in the morning, in bright afternoon light, in the evening, and at night with your lamps on. Bengaluru's light changes a fair amount through a day, and on a cloudy monsoon afternoon it changes again.
Wait until it's fully dry
Wet paint looks different from dry paint, and many colours shift as they dry. Judging a patch too early is a common mistake. Let it dry for as long as the maker states, then look again.
Check it against what stays
Hold the sample near your floor, sofa, curtains and wooden furniture, because those aren't changing. A wall colour can look right on its own and then clash with the tone of a wooden floor or a favourite fabric. If you're painting a whole flat, test in the rooms that matter most, and then look at how the colours meet at doorways.
- Two or more walls in the room
- Morning, evening and lamp light
- Next to the floor and main furniture
- Fully dry before you judge it
Testing Paint Samples on Your Own Wall — your questions.
Is it fine to choose from the colour on a shop's testing machine?
It's a good way to get a starting point. The shade is mixed from the same formula, but the shop's lighting is nothing like your room. Always put it on your wall before you order the full quantity.
Can I test on a piece of paper or board and move it around the room?
That works for a first look, and it's handy because you can carry it from wall to wall. It still lacks the wall's own texture and the effect of the surrounding paint, so make a final check with a patch directly on the wall.
How do PremiumWalls samples work at the visit?
As part of the free colour and wall inspection, we apply sample patches on your actual walls so you can judge them in your own light. The shades and sheen you approve are then written into the itemised quotation, so what gets ordered is what you chose.
What if I can't decide between two shades?
Put both on the wall side by side and live with them for a while. Usually one of them starts to feel right and the other starts to bother you. If they still feel equal, choose the one that suits your lighting at the hour you use the room most.
