If you’re designing a website that should appear “happy” on first glance, what color scheme should you choose?
Enter Cymbolism – this is an attempt “to quantify the association between colors and words, making it simple for designers to choose the best colors for the desired emotional effect”.
People can vote on colors which make them think of words like “happy”, “sad”, “sunny” or “jealous” and refer to the results to decide the appropriate color for any site.
