Vibrant Mexican Colour

We are often concerned with getting colour right to the extent that many people in my experience just close down and opt for white. White can be great of course, as can the muted heritage colours that various designer paint companies sell, but how exciting it can be to have the freedom that people have in Mexico and throughout South America in their use of colour. Of course you can get it terribly wrong but more often than not colours even from very different colour palettes will work together. Do we ever say in nature 'that's a bit of a clash of colours'? Be bold!
