I have just read some very informative articles on color from a fabulous blog I follow, Colour Me Happy by Maria Killam. Maria is a color expert and designer in Vancover, B.C. She also conducts True Colour Training and Certification courses.
I'm sure you've heard (and said yourself) the opinions on color: too warm, too cold, that green is too yellow, red is too orange. I always thought each color, whether in a paint chip or object, was categorized as such. And I've always wanted to be educated in how to tell, officially whether any said color is a warm or a cool. Believe me, I've spent too much time looking for a warmer or cooler tone.

Well, Maria has set me straight and she makes it simple. The answer is: It All Depends. Music to my ears! She explains that one color will offset the other. It's in the comparison against another color that you can say, "warmer" or "cooler," but a color itself is not necessarily warm or cold by itself.
In the photo above, Maria describes the red couch as having an orange undertone and the green pillows having yellow tones. But if other colors were placed in the room, the colors might appear cooler or warmer.
I still have much to learn about colors and am pleased to have found Maria's site. At least for now, I can stop hunting for warm or cold shades!
