In visible light communications (VLC). multi-color light emitting diodes (LEDs) have higher modulation bandwidth and better chromatic property compared with traditional phosphor-converted LEDs. For multi-color multi-input single-output (MISO) VLC systems. multiple colors of one LED are not independent with each other since they are limited jointly with chromaticity constraint. https://www.machitoorchestranyc.com/product-category/cleansers/
