My favorite color is yellow.
I love yellow too! It's a sunny color! Sunlight actually has a yellowish hue because the surface temperature of the sun!
yes, it is a wonderful bright color that looks good on everyone. I even painted a room in my house that color. 
Me too! I never really knew that yellow is actually between green and orange on the spectrum of visible light!
I did not know that. I remember mixing yellow paint and blue paint together to make green in art class. 
Me too! And I think it's amazing that RGB color models, like the ones used in tv and computer screens, actually combine red and green at equal intensity to create yellow. Isn't that wild? 
The many ways that our eyes almost play tricks on us to see different color is amazing. 
Yellow is actually a really old color. Yellow ochre pigment was one of the first colors used in art. A cave in France has a painting that's over 17,000 years old! 
I believe they used to use plants to make the pigment 
Maybe from plants containing carotenoids? Corn, daffodils, buttercups and bananas are all examples. There are so many shades of yellow!
