Is a CdS photoresistor a good detector for green light?

Operating specs for CdS detectors vary, but one reason for their enduring popularity is that they represent a reasonably good match to sunlight and the sensitivity of the human eye - so yes, they are usually very sensitive to yellow / green light.
