i trying started building real time ambient light color temperature , intensity monitor.
i know can use photoresistor light intensity can use measure light color temperature , how convert kelvin scale?
any ideas?

use light color sensor measure intensity of red/green/blue light, absolute intensity.
i've used tcs3472x series, there's tsl-something work task. there number of ones libraries supplied. don't 1 of crappy ones frequency output, can nice i2c ones, or @ least 1 analog rgb output. can em pre-mounted on breakout boards (and should, unless enjoy soldering 0.65mm pitch dfn-6 packages, color sensors seem come in...)
once red/green/blue/clear levels, need sort out how translate ratios color temperature - that's math, though, nothing specific arduino.
