Love blue tiles. Depending on how much sun and how hot your pool gets in the summer should dictate what color it is. We live in Arizona, so cool blues work best. Our neighbor has brown tile and a dark pebble tech pool. Looks like a swimming hole and gets really hot - 94% water in the summer. They obviously didn't think it through.

Excuse my duh-ness but i'm having difficulty trying to follow whats going on here. Are these two photos an exact replica of your house and pool ? If not a hasty sketch with dimensions could help a lot. By kitchen wall do you mean the wall behind the bar ? And where is the pool wall ? Are you considering the covered area as being "inside" ? Sorry for all those questions lol Sometimes when you have a design problem you need to turn it inside out or on it's head. If you can't beat it maybe embrace it by making a feature of it : i.e. contrast by having the lightest colored pool surround and a great blue or tile inside and under the overhang, something that will echo the water color ? If you have a great covered area as in photo you'll most likely be spending a lot of time there and it could be soothing to be able to sometimes retire into a darker inside. In my book, 10M isn't small and also contrasting two floor colors doesn't necessarily make a space seem smaller and confined and may in fact even open it up. Could it be that you've thought yourself into a box here ? Sometimes one needs to give it all a good shake up and see how it resettles.

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.

We have had a vinyl lined pool for 15+ years - you are making a good choice. They need no maintenance or resurfacing etc. Ours is an Aqualux liner in Caribbean. http://www.aqualuxpool.com.au/colour-range/ This colour is just the right amount of blue/green to sparkle and shimmer, look cool and inviting, but dark enough to gather and retain the sun's heat. I ran a swim school for many of those 15 years, and needed a pool that could take the knocks of hundreds of children each week, and look like something they wanted to dive into. Any lighter and the pool would look too cold, and darker looked scary! I have friends who chose the darker colours for their heat retention properties but the pools don't look as inviting, and algae builds up quicker but is harder to notice until the levels are quite high, so needing more chemicals to control/eliminate.
