Grey is a neutral color that designers have used long before it became the color of the decade.  No doubt if you have introduced grey into your interior design palette you may have noticed all greys are not created equal.  Here are a few things that may have confounded you about using grey:

1. The color grey comes in warm and cool tones and these rarely coordinate with one another.
2. Every paint company uses different pigment systems so mixing one company’s paint formula with another will not render the exact color.
3. Grey can look green, blue and red.  Blue is the most mistaken for grey.  If you can’t see through the color due to lighting or other, place the color that you suspect next to the grey to force a reaction.
4. Grey looks best when complimented with warm neutrals.  An overly cool space with too much grey is not natural and can create an uncomfortable effect.
5. It’s always fun to try new things but avoid making massive changes if you’re not sure it fits your style.  Trends are called trend for a reason.
