I am doing a project which detects helmets using raspberry pi camera.So I have blue and red color helmets.Now I need to detect both the colors and apply mask. But I know how to detect only one color at a time.

Please be more specific and post the code what you have tried with. – Mohanavel T Jan 29 '19 at 12:25

it would be useful if you could add your input image and the code you have for detecting a single colour. – Mark Setchell Jan 29 '19 at 12:32

Use `cv2.inRange()` twice and **or** the results together. – Mark Setchell Jan 29 '19 at 12:53

You just need to call the color detector 2 times with the differents colors ranges. Don't forget that use the image returned from the first detection on the second.
I have an example here
