Rainbows make me smile. I just can't help it, colour always seems to brighten my mood. For me, one of the best sources of colourful inspiration is Tumblr. In fact, I follow quite a few lovely sources of inspiration on Tumblr... find me here and be sure to check out Bows and Polka dots and Prettiness and Buttons and Snapped in the Street (for some random finds in mundane places). But for now, just enjoy some of the colourful finds I have stumbled across that put a smile on my face.
