Harsh light. Strong light on a white parasol. I love that.
Often you'll see many more parasols on a beach, looking left, right, all in different colors, but I'll choose the colors, the parasols that 'fit' together. In this case, whites, reds, pinks.
That touch of yellow and turquoise on the right helps the sunny vibe. We as painters can pick and choose, you're free to leave stuff out, to accentuate, to add. You are free.
