luminous
Luminous describes something that emits or reflects a steady, glowing light. Think of the soft, ethereal radiance of the moon in a dark sky or the gentle shimmer of bioluminescent plankton in the ocean at night. It suggests a brightness that is not harsh or blinding, but rather clear, steady, and often beautiful. In usage, the word carries a slightly elevated or poetic tone compared to the common "bright." It is frequently used to describe skin that looks healthy and radiant, or colors that seem to have an inner light. While it can technically refer to any source of light, you will most often encounter it in descriptions of art, nature, or someone's expressive, glowing appearance.
