Boho celebs for inspiration?

I've always had quite the bohemian chic/trendy look, but I'm running out of ideas and need some inspiration. I've looked to celebs like Nicole Richie and Amanda Seyfried before, but I need something new for hair (I've done everything from braided buns and scrunched hair to milkmaid braids) AND makeup (generally wear powder, mascara, curl lashes, and always, always a gloss/lipstick). Any ideas? What colors for makeup are trendy for spring?
