Another inspiration from my kitchen.
The colours result from the flash bounced off the coloured carton to the left / right side of the setup, and the forks reflecting the colours nicely. Not changed in post-processing, only slightly (20%) increased vibrance.
August 2011. At my workplace, Tilburg, Netherlands.
Canon EOS 5D MkII, Sigma 28-135 macro @ 135mm + Kenko 20mm extension tube, tripod Manfrotto 055Pro + 3D head 141RC, cable release, mini light tent, background: dark blue carton left and right, purple carton as seamless background. Flash: Canon Speedlite 580EX II handheld, in manual mode, triggered by Hähnel Combi TF remote control, manual mode: 1/125s, f/16, ISO 400.
Post-processing: vibrance, retouch, crop.
