I built an adjustable photo cell ambient light detector for my car back in 1980. I found that the photo resistor I was using was a bit more sensitive to red light than yellow light. To fix this, I painted the glass cover with a thin layer of yellow enamel model paint. This allowed me to be able to adjust the lights to come on as soon as the sun set and the sky turned red.
