dark, black, many
黎 centers on darkness and blackness, often with a sense of multitude or many people. The 'many' meaning likely extends from the idea of a dark, indistinct mass of people.
黎 originally depicted a dark, sticky substance like millet glue, combining 黍 (millet) with a component suggesting blackness. The 'many' sense may derive from the multitude of grains or people associated with darkness.
The top part 黍 looks like a plant with hanging grains, and the lower part suggests something dark and sticky. Imagine a dark, thick paste made from many millet grains, representing darkness and multitude.
For レイ, picture a dark ray of light (a contradiction) shining on a mass of people: ray -> レイ, and the dark crowd is 黎.
