There is
a Hubble image of a portion of Pandora's Cluster, and I decided to compare it with the same part of the cluster as imaged by Webb.

Pandora's Cluster by Webb.
These are the objects I have annotated:
1) A disturbed very blue spiral galaxy. It doesn't look blue in the Webb image.
2) A pair of merging blue-white galaxies. There is a red object immediately below them that isn't visible in the Hubble image.
3) A deep red distant object. It is not seen by Hubble.
4) A compact blue-white galaxy.
5) Some elongated galactic fluff. It looks blue and very faint in the Hubble image, but red and more visible in the Webb image.
6) An elongated edge-on background galaxy. It is faint and barely red in the Hubble image, but redder and brighter in the picture by Webb.
7) A yellow non-starforming ring galaxy.
8) A red background spiral galaxy, redder and brighter but rather less detailed in the Webb image than in the Hubble picture.
9) A spiral galaxy with blue arms, more detailed in the Hubble image than in the picture by Webb.
10) Thin jets emerging from a massive elliptical galaxy. The jets look blue in the Hubble image and red in the Webb picture.
11) An elongated object that looks faint and blue by Hubble but red and reasonably bright by Webb.
12) A starforming spiral galaxy with blue clusters. The blue clusters become invisible n the Webb image.
13) A background galaxy that looks blue by Hubble and red by Webb.
14) Two overlapping galaxies, one orange and one blue. The blue galaxy looks red in the picture by Webb.
15) An arc made up of cyan-colored, yellow and blue objects. In the Webb image, all the objects are colorless and white.
16) A deep red object that is barely visible in the Hubble image.
In the Webb image, very distant objects apparently always look red, which helps us judge the relative distance to them. Dusty objects look red or somewhat red. Blue objects don't look blue and sometimes don't show details very clearly. Massive elliptical galaxies are surrounded by large halos in the Webb image. More objects can be seen in the Webb image than in the Hubble image.
