Color Detection in Android Studio OpenCV

I am currently trying to make an application in Android that will detect this colors.
Left circle with RGB Values of (167,103,103). Middle Circle: (163,98,94). Right Circle: (134,62,66)
What I've done is convert the image into HSV then use
Core.inRange(HSV, new Scalar(0,0,0),new Scalar(0,0,0),ColorDetection );
How can i detect left circle, middle circle and the right circle and eventually all of them? What values should i put inside Scalar()?

oh, so I need to convert the RGB Values to HSV Values. i found this link link Can I use this for checking. Also I've found out thatCore.inRangehas a lower bound and upper bound. (i don't know what to call it sorry just started) so in the "upper bound" should i put the HSV values of the right circle?

Yes, if you are using theinRangefunction on HSV image, you should use HSV values. Also, the link provides RGB and HSV conversion values but not in the opencv range. The opencv range is different as you can see in the link I attached above
