Adafruit describes the CdS photoresistor as a light sensor whose resistance falls as light increases, and its product page gives an examp…
Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
Photo cell (CdS photoresistor) visual previewPhoto cell (CdS photoresistor)
Loose CdS light-dependent resistor for simple analog light sensing. Useful for light/dark thresholds and approximate brightness, not color detection.
TCS3200 Color Sensor visual previewTCS3200 Color Sensor
TCS3200-based color sensor module with onboard illumination. Use when the design needs color-channel detection and can handle a digital frequency output.
