Yellow isn't a very popular color in floral design. Aside from sunny sunflowers, it's probably requested the least in weddings and event work. People like to include it, but not feature it. Why is this? Is it too aggressively cheerful? Too hard to work with, too bold? I found this vase this spring in one of our local thrift stores. I didn't buy it right away. It seemed a little strange. Now it's my current favorite vase and is a gentle gateway to the color yellow. I love yellow. Doesn't everyone? Why don't we want to live with more yellow in our lives. Why? Why? Why?
In casting about on the online world, color psychology is a fascinating in- depth topic. After looking at a couple dozen of sites, the consensus was that yellow was perceived as universally cheerful, but too stimulating- that is, if the hue is bright and bold and used in large quantities. Essentially we use bright yellow flowers the way we use yellow signage; that bright pop to get one's attention. Interestingly, before doing any of this color research, I took this photo of lemony sunflowers and softened the color in Photoshop to tone it down a bit.
