What is The Colors Scale PUP?

Colors Scale is the name of a browser extension that claims to have useful functions that will allow the user to change the color properties and the contrast of web pages but has a few additions that go along with those features.

Colors Scale is intended to allow the user to alter web pages by changing color properties, hue and saturation, as well as contrast and brightness.

Along with this functionality, Colors Scale also displays features typical for adware or ad-supported apps. The extension is used to display unsolicited advertising inside the browser it is installed on. The fact that it changes colors and asks for permissions to change the content of pages you browse ties in nicely with the ability to not just change colors but also inject advertising on those pages.

The ads displayed through this type of adware extension may originate from rogue advertising networks and may link to potentially unwanted apps, questionable content, malicious pages, and scam sites.

All of this makes the presence of Color Scale or any adware app on your system undesirable. While the ads displayed are not dangerous on their own, clicking or interacting with them might expose you to further security risks.
