Unexpected? Only if you haven't heard of Piet Mondrian and the De Stijl movement.

Btw, that first image is great!

Or ketchup and mustard.

Heh, violets think alike. All I can see is a hotdog stand.

Haha, T_VIOLET! I thought of the red and yellow umbrellas used by Vienna Beef vendors in Chicago! Or, mustard and ketchup, though putting ketchup on a hot dog here in Chicago is frowned upon. :)

I do like some of these spaces, but I think when it's the standard red and yellow, in equal parts, it's a little too much for me.

or McDonald's

I always thought that red and yellow combined would be too much but what you did here is great. It made the room fun and lively.

I suddenly want a hot dog

Wow, I'm surprised that it's considered an unexpected combination. We've painted most of the walls yellow in our small house, and we have a number of pieces of red furniture. I love the combination.

Mmmm red clawfoot tub! Can't get past how much I want it... agree with the mondrian/de stijl comments, though. primaries can be very overused, too.

Am i missing something? Apart from the flower, yellow doesnt really figure in to the clawfoot bathroom.

I see red & yellow mixed together all the time. I mean look at Gryffindor's house colors. Well that's more gold & burgundy, but it's close. Hahaha

Red and yellow in decor doesn't surprise me. But the Spanish Olympic uniforms - they definitely look like they are employees of McDonald's or Chucky Cheese's... or some retro-70s airline.

Yeah, our olympic team uniforms are hideous... What can I say? It's not a spanish design, they were made by some russian guy!
