Hi Mike — great research. I am curious if CTA buttons are typically a “different” colour than the other major colour on the screen? e.g., although blue is the most popular colour of the CTA, how many of those had a general blue background (or blue as a prominent colour)?
My research in Behavioural economics would suggest that CTA’s should present as “different” than the background (to stand out — like a break in fluency).
What are your thoughts Mike — please let me know. Thanks. Cindy
