While some color changes may be subtle, others will be more noticeable as you walk around the room. Use a flashlight, shining the beam at an angle to the planks, to be able to see color changes better. Aside from discoloration in the flooring installation, damage from water can cause planks to become loose.
Depending on the type of floor you have, there may still be laminate flooring water damage. Occasional spills should be nothing to worry about. But if your floor is submerged or stays in contact with water long enough, it can swell and break down. Water damaged boards can't be fixed, but they can be replaced.
Though laminate flooring industry specifications dictate tests for laminate flooring and water where the flooring is submerged under water for a full day, irreversible damage happens long before that. Laminate flooring with open edges will maintain its original dimensions for a few hours after submerged water exposure.
Water damages laminate planks by soaking into the layers. Once inside the boards, it causes them to swell and warp. It also weakens the glue that holds them together and they can eventually fall apart.
Water under your laminate flooring can cause severe damage if not dried quickly. Laminate flooring is relatively easy to install and maintain, but there are a few things you need to know about how to dry laminate flooring with water under it.

Water under laminate flooring
If the spill isn't too bad, you might be able to extract it in time with a wet-dry vacuum. However, we recommend you err on the side of caution and remove and replace as many floorboards as were affected.
Laminate flooring is very thin, so any unevenness on the subfloor will eventually begin to show as the floor settles into position – you can find out more about this in our 'What is laminate flooring' guide. The spongy effect can be caused by a dip in the subfloor causing an air gap underneath the laminate flooring.
However, in the event of flooding or a bad sewage leak, standing water beneath vinyl plank flooring won't dry out on its own due to too much condensation that has collected between the vinyl planks and substrate or underlayment.
Using a knife, you may then make a slight incision in the affected area. Grab some wood glue, squeeze it into your incision, and then attempt to stick the laminate back down flat. You'll need to keep constant pressure on the area for the glue to hold, so find a heavy object that you can leave on it to weigh it down.
Sometimes mold on flooring is readily visible to the naked eye. You might notice patches of discoloration (usually black or green, although mold can grow in a variety of different colors) with a slimy or fuzzy texture.
Treat exposed molded subflooring with a mixture of 1 cup of borax and 1 gallon of water or an EPA-registered mold removal product. Spray the solution on the moldy plywood.

It goes without saying that not all damage is going to be visible. Water can leak in hidden places like the inside of the walls which you'll likely not notice unless and until some severe damage has been done. This is why you need to do some up close inspection to detect damage.
As noted above, water damage will usually leave walls soft to the touch, or otherwise warped, buckled, and crumbled. It also tends to cause a musty smell and dark brown or yellow-tinted stains, lines, or rings in both ceilings and walls.
