Yellow is my favorite color. It makes me feel happy!
That's nice! I know that yellow sits between orange and green in the light spectrum. Is there anything else you'd like to know about the color?
Oh interesting! What else can you tell me?
Well, I can tell you its wavelength is around 570590 nm. Would you like to know something else?
Ok, I did not know that or even what that means, lol.
Well, enough about that. I can also tell you about the primary colors.
Oh okay. I like learning so tell me about it.

Response: Sure, primary colors are red, yellow and blue.
