What color on a weather radar indicates the least severe rainfall?

In the context of weather radar, colors are used to indicate the intensity of precipitation, with each color representing a different level of rain severity. Blue is typically associated with light rain or very light precipitation, while green indicates moderate rainfall. When it comes to assessing the severity of rainfall, blue is the color that signifies the least severe precipitation.

Given this context, green accurately represents slightly more intense rainfall compared to blue, but still not as severe as yellow or red. Yellow and red reflect heavier precipitation, with yellow indicating moderate to heavy rain and red often indicating very heavy rain or severe storms. Therefore, blue accurately signals the least severe rainfall compared to the other options.
