In our category is classified in 4000K~5000k Cold White  (Cool White): in our category is classified >4500K, bluwish white.White Color in LED is made by Blue color chip + Yellow powder( well known as “YAG”), that is normal when we see LED white sometimes has a little but blue or yellow light.

Purple color in LED Lighting means the color between Pink and Purple, not real Purple, real purple should be ULTRA VIOLET and only for medical use because UV is not bright enough for bulb

We demonstrate a perovskite single-phototransistor visible-light spectrometer based on a deep-learning method. The size of the spectrometer is set to the scale of the phototransistor. A photoresponsivity matrix for the deep-learning system is learned from the characteristic parameters of the visible-light wavelength, gate voltage, and power densities of a commercial standard blackbody source. Unknown spectra are reconstructed using the corresponding photocurrent vectors. As a confirmatory experiment, a 532-nm laser and multipeak broadband spectrum are successfully reconstructed using our perovskite single-phototransistor spectrometer. The resolution is improved to 1 nm by increasing the number of sampling points from 80 to 400. In addition, a way to further improve the resolution is provided by increasing the number of sampling points, characteristic parameters, and training datasets. Furthermore, artificial intelligence technology may open pathways for on-chip visible-light spectroscopy.
