A property manager forwarded me the warm greige her board had approved off a paint chip and asked why the first finished floor looked so much darker and greener than the sample they signed. Nothing was wrong with the paint. A colour behaves differently at the scale of a hallway — under the building’s own light, in a given sheen — than it does on a two-inch card. This post is for condo boards and property managers about to commit a whole building to one colour: here’s what I check before the first wall gets rolled.
1. A colour gets darker and stronger the more of it you put on a wall
The most common colour surprise isn’t the painter’s mistake — it’s scale. A two-inch chip bounces a little light at your eye. A whole corridor reflects the colour off itself, floor to ceiling and around every corner, so it concentrates. Mid-tone greys, greiges, and “soft” greens come back deeper and more saturated than the chip promised.
There’s a number that predicts this, and most boards never ask for it: LRV, light reflectance value. It runs from 0 for black to 100 for pure white and tells you how much light a colour bounces back. A corridor colour in the 55-to-65 range stays light and forgiving; drop into the 40s and the same windowless hallway feels like a heavier, darker room than anyone signed off on.
What to look at: Ask for the LRV of the colour on the table, and never approve a building-wide colour off a chip. Get a large drawdown — at least two feet square — and look at it on the actual wall.
2. Your building’s lighting changes the colour before anyone picks up a roller
A colour is only “that colour” under the light it was chosen in. The fan deck got approved in a sunlit boardroom; your corridors run on warm or cool LED, your stairwells on cooler fixtures, and many of those spaces never see a window. The same greige can pull green under one colour temperature and faintly purple under another, and a clean white can go blue in a cool-lit stairwell.
That’s why a colour that looked perfect on the sample can feel “off” once it’s up, even though the can is exactly what was specified. The paint didn’t change. The light did.
What to look at: Tape your large samples to the real walls and view them under the building’s own fixtures, mid-morning and again late afternoon. If a space has no daylight, judge it only under the light it actually lives with.
3. Sheen is a durability decision, not a taste decision
Boards debate colour for weeks and decide sheen in a sentence. In a high-traffic corridor that’s backwards. Flatter finishes hide imperfections and roller laps beautifully, but they’re harder to clean and can burnish — go shiny — where hands and carts rub. Eggshell or satin scrubs and wipes far better, but it catches side-light and shows every lap mark and touch-up along a long, straight wall.
For occupied common areas I’m usually after a washable finish that survives cleaning without flashing when it’s touched up — typically a quality matte or low-eggshell built for commercial corridors. The right sheen is the one that still looks even after three years of cleaning, not the one that looked best on a dry sample.
What to look at: Ask what sheen is specified and whether it can be spot-touched-up later without leaving a visible patch. If nobody can answer that, the sheen hasn’t really been chosen yet.
4. Specify the colour so every floor — and every touch-up — actually matches
A colour that lives only in an email as “the greige we picked” will drift. Across fourteen floors, between paint batches — or worse, between two brands’ “equivalent” matches — small differences add up until floor 9 doesn’t match floor 2. A year later, when a mover gouges a wall, whoever patches it has to put back the exact colour, sheen, and base, or the repair flashes like a bruise.
The fix costs nothing: pin it down in writing. Manufacturer, colour name and code, sheen, and base, recorded in the contract and kept in the building’s maintenance file. That one page is what makes a touch-up in year three invisible.
What to look at: Get the full colour specification in writing before work starts, and file it with your reserve and maintenance records. If you can’t find that sheet today, your next touch-up is a guess.
What to do if you’re choosing a colour for a whole building
Don’t approve a building-wide colour from a chip in a boardroom. Get large drawdowns, look at them on the real walls under the real lights, decide sheen as carefully as colour, and write the whole specification down. Do that and the finished building looks like the colour the board actually chose — on every floor, for years.
I help condo boards and property managers choose and specify paint colours, and I walk buildings before a repaint, across Ottawa and the surrounding communities — Kanata, Nepean, Barrhaven, Orleans, Stittsville, Manotick, and Westboro. If you want a second set of eyes on a colour before it goes building-wide, I’ll tell you how it will actually read. No charge.
