From my bedroom window I often see spectacular clouds flow by, such as these: a white cloud, grey swirls of clouds and a dark one predicting nothing good, all on a perfectly blue sky background.
Behind our house (my view) is the east, so when the sun sets I always get to see the reflections of the sunset colours on clouds in the east. This pink one was fantastic!
Other than clouds, flowers can be breathtaking as well. I liked these flowers in my grandmother’s garden, especially the contrast between the purple flowers and the red/orange marks.
