Gray is tougher than you think, isn't it? You could add some orange to take away the bluish tint for the second coat. Also, orange accessories would help neutralize the blue undertone.

Why not just take the what's left in the can back to the place you bought it and ask them for their help? I'm sure that, being in the paint business, they'll be able to easily add to it to give you a less blue outcome.

I would agree with amysrq that you could either alter the paint or use blue accessories to make the paint look less blue. I have peach/pink laminate countertops in my kitchen (that I hope to someday soon remodel). The previous owners painted the kitchen a light green which (being the opposite color of red) made the countertops look even more pink. I repainted with a deep red which overpowers the countertops such that they almost appear beige/almond now. I suspect the same trick will work with blue-gray paint.

Yes, ask the paint guys to "dirty up" the blue with dull brown-orange pigments...look at the chips and find one that is less blue and more neutral, and ask them to head in that direction.
Because orange and blue are opposites on the color wheel, they intensify each other. When orange pigment is added to blue, it neutralizes both colors. That's why grays are so different. Some are made from red and blue-green; some made of yellow-green and purple, some by mixing blue and red-orange.
(It's also why the gray jacket you bought to go with your gray flannel pants might not match!)

Since you need to do a second coat why not pick up a difference color for it? Just write off the half gallon. I did this with a bathroom. The color I had choose turned out to be a little too mint green. I find another color that was close but not as minty and used it as a second coat. It worked beautifully.

Thanks all! I did go back to the store and have them mess with the color a bit. I think I'm going to like the new color better (I did a quick test splotch) but I don't think I'm going to have enough for a full second coat. I'm actually using this in 2 different rooms so I'll probably use what I have left in one room and figure something out for the other. Sorry it took me so long to respond -- gardenweb was giving me guff when I tried to log in.

Thanks for this post! I followed the orange advice and it worked.

How much orange was added to tone down the color?

please let us know how mich orange was added to the paint

Same thing happened to me. I took half the jar of paint back and they actually added some gold to it, so it isnt so blue. This was at Sherwin Williams. He said he would add just a few “drops” of gold to the remaining amount I had

Same problem here! I purchased “Morning Fog” in the Sherwin Williams showcase paint at Lowe’s. Took this advice and went back to Lowe’s. She added 20 drops of orange. Some brands don’t have orange (mine did) so in that case you would use 10 yellow and 10 red drops. It made such a difference. I haven’t put the updated color on the walls yet (just did a sample so far) but I will update with pics when I do!

**updated with pic*** WOW, right?

I have the same issue BUT the room is huge and was painted years ago. Until I re paint, how can I GREY up the wall color? Do I really use blue accessories/ wall art? <— this seems so counterintuitive for me, but I’m not in the design field!!!

Same problem here... I’ve used the same color I just painted in a different house, so I knew I liked it. Only thing is... the trim and cabinets are completely different. Last house was white trim and cabinets. This house, natural red oak (temporarily)... needless to say, the paint in this house looks light blue against the oak, when I wanted a light gray.
