Purple Flowers

I sure like these purple flowers, but don't know what they are. In a burst of inspiration I tried a new angle and I liked the composition. It's difficult to take because of the direction of the sun. But one day I happened to catch the scene right before the sun came up over the hill behind them.

Purple flowers, like rocks, look best with a cool tone (white balance) instead of warm. Also I think purple flowers, like white flowers, might be best shot on a cloudy day. Better color rendering. Purple can be a difficult color to get correct in-camera. I often get blue instead of purple in-camera. The color fuchsia or hot deep pink is difficult too (just pink is ok). So is a wine color. A hot deep pink and a maroon wine are often rendered red in-camera,no matter what white balance I use.

The flowers are purple liatris.
