Colour manipulation

I liked the colours on this photograph, I think that they looked good originally but the background was a bit odd in relation as it was quite a dull colour. I think the colours look more striking with a black and white background

I really like the original colour of the sky as the blue gets lighter and it's very clear with no clouds. However I think that it looks nice when it's all based around one colour, it makes it look like it was taken with a sepia sort of filter, which I really quite like.
