Description
Issue Summary
The {{contrast_text_color}} helper returns incorrect text color for many
backgrounds due to a typo in textColorForBackgroundColor from @tryghost/color-utils.
Root cause
In @tryghost/color-utils the YIQ formula uses .b() instead of .blue():
Fix
PR submitted to TryGhost/SDK: https://github.com/TryGhost/SDK/pull/905
Steps to Reproduce
Use light color with the {{contrast_text_color}} helper — the returned contrast color will be white instead of black.
For example: #dacafe, #ffa5b1, #a3e6ff
