Legos are some of the best building toys that have ever existed. The fun and creativity that they bring and inspire are unmatched by pretty much any other building toy on the market and it’s likely to stay that way for a long time to come.

Legos are no longer just a toy for kids however as there are many adults that love playing with them and also many people who are avid collectors of the specialty sets. 

There is one thing that Lego owners, and especially hardcore collectors, may worry about and that is if Legos fade in the sun. 

LEGOs, just like any other toy or item, will eventually fade if left out in the sunlight for too long. They can also become faded if left inside but in front of a window or door that the sun comes through. 

Thankfully, they do not fade quickly, and there are methods that you can use in order to prevent the premature fading of your beloved Lego bricks. 

The easiest way to avoid fading is to never leave them outside and also never store them in front of a window in direct sunlight. 

If you are interested in learning more about why LEGO bricks fade and how you can prevent this from happening in the future you will want to continue reading.

How Does The Sun Damage Legos?

Lego bricks are made to last for years without suffering from any sort of discoloration or fading, but they can only maintain their beautiful appearance if you take care of them by avoiding strong lights, especially light that comes from the sun.

Fading does not happen quickly though, but if you constantly leave your Lego bricks in a place where they are exposed to the sun’s light they will eventually begin to fade and lose their true color. While sunlight can lead to the discoloration and fading of your Lego bricks, bright indoor lights can also lead to the fading of your bricks.

Aside from bright sunlight and indoor lights that may be a bit too harsh on the bricks, having lights set too close to your Lego pieces can also lead to them fading or losing their true colors. Even bricks that are kept in a room that gets indirect sunlight can suffer from fading and discoloration if the glass of the windows does not block the harsh UV rays that the sun gives off.

The Lego Group manufactures their bricks to be very resilient, and if taken care of they will last for years and still maintain their true color. However, when not taken care of properly they can fade and lose their proper appearance which they originally had.

This is especially apparent in white Lego bricks. If exposed to too much sun they will turn a yellow color, and begin to look like another color entirely. Blue bricks can fade down to a dirty brown color if left out in the sun too long, and red bricks will begin to look pink.

Be aware that all Lego bricks will eventually suffer from faded colors if left out in direct or indirect sunlight for extended periods of time, or if exposed to artificial light that is too harsh. It’s best to take preventative measures to lessen the chance of your bricks becoming faded rather than run the risk of them fading and becoming unappealing or unusable.

How to Prevent Legos From Fading

One of the best ways to prevent your Lego bricks from fading and losing their color is by making sure that the area you wish to keep or display them in is not exposed to any strong sunlight throughout the day.

If you notice that the room you plan on displaying your Lego creations inside of gets hit head-on by the sun’s light at some time during the day, it is best to either use curtains to block the sunlight or to simply choose a different room to keep your Legos in. 

Even if the sun only shines into the room for a short time every single day it can add up through the months and years and eventually fade your Lego bricks.

Any artificial light that you have present in the room you choose to display your Legos in should also not be too harsh and should be kept a good distance away from the bricks themselves. 

You will notice that many AFOLs (Adult Fans of Legos) choose to keep their Lego collections inside of a room with very soft light.

These rooms that they keep their collections in also tend to not have any sort of window, lessening or entirely eliminating the chance that their Legos will fade due to direct or indirect sunlight. The artificial lights that they choose to use in their Lego rooms are also very soft, further ensuring that their precious Lego bricks do not suffer any sort of fading or discoloration.

If you have no choice and do not have a room without windows available then you can instead opt to keep your Legos in a room that faces the North or South of your house. This will prevent direct sunlight from shining in through a window and help to keep your Legos in the best shape possible.

You may also decide to simply keep your Lego display facing away from the window, so that even if you decide to keep the window blinds open and allow the sun to shine in you lessen the impact that the sun’s light will have on your bricks.

After taking the necessary steps to ensure that your Legos are protected from both direct and indirect forms of light that could lead to fading and discoloration, you should also make sure to check on your Lego creations every couple of months just to be extra sure that they are not fading.

Check the sides of the Legos that are exposed to any possible light and compare them to those which are hidden from view. If you see a noticeable difference in color then it may be time to find a new display area for your Legos in order to prevent further fading or you can change around the artificial lighting of the room if no sunlight has been present. 

Other Effects the Sun Has on Legos

Aside from simply fading the colors of your Lego bricks, sunlight can also serve to damage the brick itself. Bricks left in the sun for too long will eventually become brittle and are much more prone to breaking than bricks that are kept hidden away from the sunlight.

Because Legos are made out of plastic they are very susceptible to damage from the sun. The quality of Lego bricks is very good, but they are not safe from the harmful rays of the sun. 

This is especially true long term. 

Even if your bricks do not become brittle after being left in the sun for too long, they can deform and change shape if they are heated up enough by the sun. This can lead to bricks no longer fitting together, essentially making them useless.


Just as with almost any other item, Legos will fade if left in sunlight for too long. Not only can sunlight fade and discolor your Lego bricks though, but even artificial light that is too harsh can lead to your Lego pieces becoming faded and discolored.

Simply follow the tips listed in this article and you can ensure that your Legos will stay as beautiful as possible for a very long time. 

Just remember to keep them away from direct sunlight and harsh indoor lights and you should be all set!
