Can Adobe Illustrator or Photoshop record selection history for undo?
Selecting multiple things with "shift" key sometimes lost all selection when "shift" key failed by mistake. So I need to work from start again.

I do not understand what you are referring to.
In Photoshop Undo does indeed change the last selection. If you mistakenly deselect things, undo will reselect them. Basically, all Photoshop's undo does is take 1 step back in History. If that step backwards involves a selection.. it's undone/redone.
In Illustrator after creating a selection you can use the menu item
Select > Save Selection and then recall that selection layer via
Select > Load Selection. Because Illustrator is object-based not pixel-based, selections won't undo/redo the same way they do in Photoshop. And Illustrator has no "history".
In Illustrator, if your selection is that complex, try using the Layers panel, and/or saving the selection as you add & remove objects so if you lose the selection you can reload the last saved selection rather than start over.
In Photoshop, use QuickMask or even create a new alpha channel. Edits to quickmask/alpha appear in the undo history subject to Ctrl-Z.
Yes, save your selection often.
In Photoshop go to Select > Save Selection… and set it to replace the old selection each time you save (Replace Channel… see image). Selections are also saved as Channels in the Channels Panel behind Layers and Paths.
In AI you can save the selection, but I did not see an option to replace the previous selection, so you may need to rename it each time you save. Or like user75926 said, make a separate layer for your selction.
This way, if you lose your selection, you can hen Select > Load Selection… to get it back.
A quick solution might be to use the select similar option. Particularly if the object's you're selecting are the same colour.
Edit. This is specifically for illustrator. My suggested work around in photoshop is to use the magic wand tool that would automatically select the colours, save that selection as a mask and then extract each colour from its various layers with a bit of cnp.
