Hello Cola, thank you for your feedback. We're sorry to hear your paint's finishing color didn't turn out as expected, as the color looked more lilac/blue than light gray. To verify that the color was mixed correctly, we'd suggest checking that the physical color swatch matches the paint dab on your can's lid. If the colors match, the paint was properly mixed, and the color is correct. In cases like this, the best solution would be to recoat in a different color. If the swatch doesn’t match the dab on the can’s lid, the color was incorrectly mixed, and we'd suggest recoating with new paint tinted to the correct color. Please keep in mind that different lighting will affect how a color looks and that our online color palette display may vary slightly from the actual colors due to variances in monitor settings. Customer satisfaction is important to us. Please feel free to reach out to our Customer Care team directly if you have any questions or need assistance. Our team will be happy to help! Have a great day. –Joanna
