Yes, the drop test where you compare the color to a range of yellows turns first orange and then red as the chlorine level gets above the range the test was designed for. Red/orange is quite high. Without a color standard to compare to it is impossible to say just how high but quite likely well above 10.
This is when the FAS-DPD test in the TF Test Kit and Taylor K-2006 comes in handy. They can give accurate readings up to 25 or more.
