July 17: rooftop twilight
The evening after final review offered up a feast of gorgeous cloud colors, as if in celebration.

You can see the shadows of other clouds on these clouds.

Diffuse pink glow above the antennas.

A mauve cloudbeast.

Another look at the substructure of the roof.

A quick peek across the terrace next to ours.
0525

A rather fetching composition of dissolving cloud fragments.

Pink sun on higher clouds over the church spire. I also like the mix of red and green on the spire's roof tiles, which I'd forgotten about or maybe not noticed before.
0532

A procession of gray cloudbeasts.

Diffusing wisps to the north.
0536

Just a little bit of pink left over the antennas.
0539

Our very own antenna over the stairwell roof.
0545

Clouds seemingly growing diagonally without bound.
0553

Light gray, dark gray.
0554

To the northwest, with Tibidabo and the Collserola tower on the horizon, cirrostratus turned a ruddy brown.
0559

Huh, the antennas are pointed toward the tower. Hmm.
0562
![](pix/rooftop-twilight/0562.jpg)
Dancing cloud.
0563

Behind the Palau Nacional you can see the Olympic stadium tower, almost blending in with the sky colors.
0570

The eastern clouds seem to have re-pinkened latterly, somehow.
0585
![](pix/rooftop-twilight/0585.jpg)
Rorschach clouds.
0587

The northwestern cirrostratus then developed striking maroons and purples, in combination with the open sky.
0589

A cool-to-warm spectrum beyond the antennas.
0592

Now the clouds were pink from the red western sky rather than from the direct sun.
0598
![](pix/rooftop-twilight/0598.jpg)
All sorts of yellows, greens and purples can be found in this sky on careful inspection.
0613

The sunsetward color stayed vivid as it deepened.
0620

Montjuïc lighting up as the twilight fades.
0629

As dusk approached, the Palau's rays came into view.
0631

Still some color variety remaining to the northwest, in an unusual-looking red-gray-blue progression.
