If you ever need to create a custom colored LED you can dip a white led in "Great Glass", sold at many craft stores, a glass tint for simulating stained glass. It comes in a complete spectrum and can be mixed to create most any color you need.  One thing to note if you are going to a cold color such as blue or green start with a cold white led.  If going to red, magenta, orange, use a warm toned led.   Another option is to use Roscolux gel filters which come in a complete spectrum also.   https://us.rosco.com/en/products/catalog/roscolux
