The \u003cstrong\u003ediffused (frosted) lens\u003c\/strong\u003e scatters light from all three elements so they blend smoothly into a single uniform color rather than appearing as three distinct spots.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ecommon anode\u003c\/strong\u003e configuration means the shared positive lead (Lead 2, the longest pin) connects to your supply voltage, and each color is switched on by driving its cathode pin LOW.
