You asked us a question. How do colors affect our moods?
I'm green with envy. I'm so angry I'm seeing red. I'm feeling really blue today.
We definitely tend to link colors with emotions. There's been plenty of psychological and social research on how specific colors actually influence our moods and actions.
The effects of color aren't written into our DNA. They are set by personal experience. You might be able to imagine some universal associations. For example, a feeling of tranquility might remind you of the calm blue of the sky. But for Joe Schmoe, blue might also trigger anger and fear. Perhaps it reminds him of the jacket on the playground bully.
The cultures we live in also tend to dictate how we read certain colors. We often think of white as representing purity and innocence. But in some cultures, it's the color of mourning.
The lack of agreement hasn't stopped advertisers from using those cultural differences. They try and influence our buying decisions. Office managers might use color information theory to increase productivity in the workplace.
Whether these colorful tricks work or not is up for debate.
