Brief: Use one colour to add life or drama to your shot.
I’m not very good at following instructions and when I saw this in the greenhouse it took by breath away. I was not expecting the true leaves on the carob seedling to be such a vivid red and against the strong green leaves it just stands out. But the image also needed some kind of background so I set it against some neutral hay. So I’ve kind of used three colours. Green and red are kinda opposite on the colour wheel so I think I may have gotten away with it.
