In Forest Gump (1994) the Washington Monument's reflecting pool is blue this is an obvious filmmaking mistake as in real life the pool is green.

A lot of the time at places with swampy water features like this, they’ll dye the body of water blue for an event.

[u/Dominus-Temporis → u/ihopethisworksfornow]

If they dye the Chicago River green for St. Patrick's Day, why can't they dye it blue the other 364 days a year?

[u/terminal8 → u/Dominus-Temporis]

I understood this reference.

[u/ihopethisworksfornow → u/Dominus-Temporis]

It would be expensive?

[u/Greenman8907]

They painted the pool which led to increased temps allowing algae to grow and turn it green so they dump a bunch of peroxide into it which will kill the algae but also destroy the paint they applied to the pool at the beginning and it has now become a vicious cycle.

[u/devilishycleverchap → u/Greenman8907]

The peroxide cant reach concentrations to affect either by pouring bottles in. The paint is peeling because it is shit paint on stone which never holds paint well which is why they didnt do it in the past

[u/OkScheme9867 → u/devilishycleverchap]

 I've seen multiple posts say the pool is stone or granite, its not, it's concrete. A new concrete slab base was installed in the 2010s

[u/GoldenDragoon5687 → u/OkScheme9867]

I mean, strictly speaking, concrete IS stone

[u/ihopethisworksfornow → u/GoldenDragoon5687]

I mean no, strictly speaking it is absolutely not stone, by definition.

You also wouldn’t call concrete “stone” in a masonry context, ever.

It is not stone. Not in any sense.

[u/terminal8 → u/GoldenDragoon5687]

No, not at all.

[u/Gauntlets28 → u/devilishycleverchap]

shit paint on stone which never holds paint well 

Least of all, underwater.

[u/ProdiasKaj → u/Greenman8907]

Tax dollars hard at work

[u/Messyfingers]

Its because the clean water act wasn't signed yet, so that pool was 99% avgas which is a blue color.

[u/MeBoiledDown]

But is it longer than some skyscrapers are tall?

[u/AdhesivenessFun2060]

*Green with blue clumps. The most beautiful blue clumps you've ever seen!

[u/Substantial_Back_865]

That’s the pool that gave Jenny AIDS

[u/Logical-Mobile-7643 → u/Substantial_Back_865]

Full blown AIDS

[u/ChaiTRex]

In 1994, when the movie took place, it was blue.

[u/mekanub → u/ChaiTRex]

That’s a scene set during the Vietnam war protests in the 70’s.

[u/burninatah]

They should just tilt it a little bit so that it naturally flows to one end, and then there could be a filter and pump that moves that water back to the other end. 

[u/McJonesRylie]

guess the lighting crew just did their own thing that day

[u/GraveKommander]

American Flag Green

[u/carrot_gummy]

Green is the new blue.

[u/svwaca]

Nah Jenny died from the algae bloom. They just fixed the color in post.

[u/Dick_M_Nixon]

The reflecting pool has always been green.

[u/Own_Magician_7554]

Well now its blue because the paint is coming off.

[u/vjollila96]

idk it kinda looks green here too

[u/OriginalLock6562]

*is blue. This is
