The Lego Nolan Posted September 22, 2015 Posted September 22, 2015 I have a couple pieces that I would like to be in a different color. I'm interested in making them just a bit paler. These aren't pieces LEGO has made in any similiar color. Anyone know any ways I could do that? Quote
Lyichir Posted September 22, 2015 Posted September 22, 2015 I have a couple pieces that I would like to be in a different color. I'm interested in making them just a bit paler. These aren't pieces LEGO has made in any similiar color. Anyone know any ways I could do that? This is certainly an interesting question. I've heard a lot of people talk about how to prevent or repair discoloration, but I don't think I've ever heard any discussion on how to cause it. The first thing that comes to mind would be just letting the sun do the work by leaving the sets in direct sunlight, but not only could that be a slow process, but it'd also be hard to keep consistent. Anyone else have any better ideas? Quote
MajorAlvega Posted September 23, 2015 Posted September 23, 2015 Maybe an ultra-violet lamp? Like those cabinets used to make Printed Circuit Boards. Quote
Vodnik Posted September 23, 2015 Posted September 23, 2015 Use the same method as for de-yellowing of old bricks. Place your bricks in hydrogen peroxide solution and leave it in direct sunlight. After several hours - possibly even a couple of days - the colors will fade somewhat. Quote

AmperZand Posted September 25, 2015 Posted September 25, 2015 (edited) I don't really get it. How do you do the same to achieve completely different result? It's not the same. The hydrogen peroxide is a whitener. The sunlight just locks the new colour in. You can speed up the process if you add Vanish Oxi Crystal White to the hydrogen peroxide. What normally takes hours can be achieved in minutes which is handy if you live in a country like mine where the sun only shines three times a year. It's very important that you use a glass without a lid if you add a catalyst like Vanish as the mixture will get hot and release gas. Edited September 25, 2015 by AmperZand Quote
