Google Has Been A/B Testing Link Colors (Again) And This Light Blue Didn't Pass

It's been a decade since it was first discovered that Google has famously tested those 41 shades of blue. Last month I discovered that they began experimenting with link colors on their search results screen - once again. This time Google tested a lighter blue with a lower contrast which turned out that they rejected (most likely due to a negative experiment result). View Leak

Zalando has run a simple experiment on their product page where they challenged their existing orange add-to-cart button against a black one. One month later, the black button was rejected even though the black one had a higher contrast ratio.   View Leak

For each pattern, we measure three key data points derived from related tests:

REPEATABILITY - this is a measure of how often a given pattern has generated a positive or negative effect. The higher this number, the more likely the pattern will continue to repeat.

SHALLOW MEDIAN - this is a median effect measured with low intent actions such as initiating the first step of a lengthier process

DEEP MEDIAN - this is derived from the highest intent metrics that we have for a given test such as fully completed signups or sales.
