The Tuesday a bridal shop in Savannah showed me my screen was lying about cream
Spent two weeks designing a save the date for a couple in Savannah and it looked like warm cream on my monitor the whole time. Drove the proof to the bridal shop on Broughton Street so the mom could okay it, and she held it up to their window light and it was straight up GREY. Turns out my bedroom lamp sits around 2700K and was painting everything warm before it ever hit the file. What cheap light setup are you all using to check proofs before you send them out?
Grey is a thing though, and that's kind of the point. Cream is a warm, yellow-ish color, so if the file was actually cream, window light should show cream, just maybe cooler or flatter than you'd like. If it went fully grey, that tells me the file itself had a grey cast baked in and your lamp was just hiding it the whole time, which is a totally different problem than a lighting mismatch. So the real lesson here isn't "buy a better bulb," it's that you need a neutral reference next to the proof, like a white sheet of paper or a grey card, so you're comparing the ink to something real instead of trusting your eyes in a room that lies to you. A cheap daylight bulb in a plain lamp and a piece of printer paper will catch that every time without spending anything.
