Colour Popping/Selective Colour

Brief

In this contest I would love to see your best photos showing the technique of colour popping, also known as selective colour. With this technique, the photo is in black and white, except the subject, or part of the subject, which will be in colour. The subject can be anything at all, but it must show a colour-popped/selective colour element within the image. Try to do this creatively, rather than just reducing the sliders for other colours in photo editing. I look forward to seeing your best images.
