Colour effect

good evening! I encountered your problem just a couple of days ago and started looking for me to expand the color base. I did not find anything normal, except for the site. https://create.vista.com/colors/color-names/chartreuse/  I hope I helped you.
Good evening

@Raghul.P22763242590s thanks for sharing your feedback. Right now, we offer 5 filter color options, as explained under Apply filters Help topic.

I'll check with our engineering team internally to see if there is a possibility of adding more colors in the future releases. 

However,  you can also file a bug or feature request online. Adobe Scan team appreciates feedback and ideas.
