How to match RGB images using match multiple geometric patterns

[Hayui]

Good day! I'm trying to match eye colors using match multiple geometric patterns but I can't do it since the output in match multiple geometric pattern is in black and white. Is there a way wherein I can change the output to RGB instead of black and white? Thank you!

Usually pattern matching starts with converting RGB to greyscale!  Color adds several additional dimensions to the problem.

I changed the vision info to "color template", but there's an error with its template. How am I going to fix it? Also, attached below is the output image of the load button, how can I change its palette to RGB? Thank you.

What is the error you are getting?

I think it is similar post here: https://forums.ni.com/t5/LabVIEW/Is-it-possible-to-match-multiple-color-patterns/m-p/3339603

-Geometric pattern works on gray scale images(what you told black and white)

-Color pattern matching works on Color image(e.g., RGB)

Be clear what you want to do

-You want to do Geometric matching then the input and output will be grayscale: http://www.ni.com/example/30535/en/ 

-If you want to do Color pattern matching check this example: http://www.ni.com/example/30548/en/ 

-Each type of template carries different information so you cannot mix and use.
