What is the color for rainfall rate less than 1 mm/hr in WX mode?

Explanation:
WX mode uses a color scale to show how much rain is falling. The scale starts with black for areas with negligible rainfall, and then colors progress from green (light rain) to yellow (moderate) to red (heavy) as the rate increases. Therefore, rainfall rates under 1 mm/hr are shown as black because they’re essentially negligible, allowing you to quickly distinguish rainfall that is truly occurring from the clear background. If it were colored like green or yellow, it would imply detectable rain where there isn’t meaningful rainfall.
