How can I make my kitchen cabinets so that I can see what’s inside?

You can paint the inside white.

Removing doors will help, or adding puck lights that are battery operated in the insides will let you see what's there

Cut out the front panel and add glass or other decorative backing.

You may be able to buy some motion sensored light strips, to put on the inside of your cabinet.

I would paint the insiides a cream color or even a light tan -- stay away from pure white though --it will 'yellow' over time. On the more tech side...consider adding some of the press on LED light strips to the very back underside of each shelf -- they are pretty in-expensive and have a very LONG life. Hope this helps.....John

Assuming their stained dark, you can always paint them or you can strip the finish and stain off and lightly sand and stain a lighter color and relacquer . Just depending on what you want?

Paint the inside of the cabinets are put Contact paper inside.

Had the same problem in my pantry cabinet. I bought a battery light and just set it in front of the cabinet shelf I did not attach it, that way I can move it from one shelf to another. I love it.
