It is quite common for people not to be able to see the difference between green and red. For those people, editing automation rules was significantly less user friendly. That’s because when people are formulating an automation rule expression, condition or action, the color of the text they enter is red as long as it is invalid. The color changes dynamically as soon as the text becomes valid.
To help people who are colorblind benefit from the same dynamic feedback, text is now underlined with a dotted line as long as it is invalid.
As soon as the text becomes valid, it changes color and the dotted underline disappears.
This makes it easier to spot mistakes while editing automation rules, even for people who are not colorblind.
