七色

1. Origins, structure, and basic meaning

• Structure: 七色, read なないろ, means seven colors or rainbow colors.
• Basic usage: Use it to describe rainbows or multicolored lighting effects.

2. Common pitfalls and similar expressions

• Two modifier patterns
  • 七色の modifies a following noun. The example 七色の虹 describes a seven-colored rainbow.
  • 七色に modifies an action. The example 七色に輝いている describes shining in rainbow colors.
• Number and colorful appearance
  • 七色 can identify seven colors, but can also evoke a rainbow-like range, as with the fountain in the example. Not every use reports an exact measurement of color count.
