Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

So white and yellow for staying cool, every other color heats up.

Tradeoff is dark colors absorb more UV so it provides better protection from the sun

Umm…

~~Reflection is just as effective as absorption. As long as the UV isn’t passing through the fabric into you, you are fine.~~

Well butter my biscuit, I might be wrong. There are other of factors to take into account, but it makes sense that, the portion of light that does make it through a light fabric will keep on reflecting inside the garment until it is absorbed or escapes back out. Like a photography light box.

Skincancer.org is my source for darker colors being better protection

I don't have the highest degree of confidence in it but it makes sense to me that absorption matters more than reflection because a lot of the reflected UV will be going through the shirt and onto your skin

That's why materials like linen aren't as good for UV protection. They're light weaves and let a lot of light through, still
