Or at least parts of primula flowers... I cropped out the bright centers of flowers, so it wouldn't take over the dark indigo...
There is a problem with those dark blue tones, where does it go from blue to indigo and then to purple? This flower looked so indigo at the market place in the shade, next to purple pansies. And then I looked at it in the sunlight close to other primulas I have and it looked purple, and then, next to violets it was totally blue again... I guess that would be precise definition of indigo: dark blue with a hint of purple...
