Hi everyone I've made a Discord for further discussions: discord.gg/4DWvahY94U. I'm also more likely to respond there as TH-cam comments aren't always the most ideal places for conversation. Thank you!
In The Laser lab my dad worked the walls and ceilings were painted in low reflective black to minimise the risk of the high energie Laser light bouncing of the wall and into the eyes of the employees. When you work with lasers of category 3 (The blink of an eye is enough timefor the laser to damage your retina) you want to be sure that the light is only were you intended it to be.
Got to know about your channel through Mr. Tom Scott's channel...and i can definitely say a 100% that i don't regret hitting the like and subscribe button after watching the ' history about exit sign' video...people like you deserve more recognition.. keep up the good work:)
Beth, I hope you see this and maybe give me an answer. I love the lighting(both interior and exterior) in the first part of the day from 9:30 AM to 12:00 AM but absolutely hate the interior daylight from 14:00PM to 18:00PM. The early evening(before artificial lighting is on) is ok. Is there a way to plan interior lighting of a living space in a way that it changes the lighting to that of the first half of the day? Or maybe nullify the yellowish gold light of the 14-18pm? I live in an urban area 52* North Lattitude.
In kindergarten we got to play with shapes and colors, now after many years of school and university, I can proudly say that my future consists of playing with shapes and colors. Although in my case they'll probably always be digital and since I'm like graphics and can program I'll have to know a ton of math. At least a real life designer gets to play with physical shapes and colors.
Perhaps you can talk about luminosity functions and how they affect color (both photopic and scotopic). It is not just the energy at a given frequency but the distribution of those frequencies in terms of amplitudes.
I guess that could be a "perfect mirror" in that case, but I'm not sure if that actually exist. Maybe there is something close to that in a lab somewhere... A normal mirror absorbs a few percent of the light depending on the type of glass and the reflective material on its surface. It also needs to have an even surface without any microscopic structures that spread the light in random directions, or it would be pretty useless as an mirror. :)
Actually, a mirror ironically has a very low LRV. I can't find a source right now but I remember my lighting design professor telling us mirrors usually have LRVs of less than 10. The problem is because a mirror can only reflect light in a focused direction - whereas high LRV require the surface to be able to diffuse and scatter light in all directions - which is why a bright white wall is usually the best at that.
I'm surprised that Contrast is only expressed as a ratio, since, with this formula, even a dark grey of LRV10 would clear a 70% contrast against the LRV3 Tricorn Black and Tricorn Black would itself be considered over 70% over Vantablack. I don't have swatches on hand, but it seems unlikely that either of those combinations would be anywhere close to distinguishable by people that rely on these guidelines.
Actually - something I forgot to include is that many accessibility guidelines stipulate that the lighter colour (B1) needs to be at least LRV 45 - this would eliminate the problem of using two very dark colours to achieve the 70%. Thanks for pointing this out.

This brings me back to my environmental control systems classes in architecture school. Thanks for the excellent refresher!

Betty's back!
Also, this was very interesting! It honestly never really occurred to me that color can have such an important, non-aesthetic purpose!
Glad to see you're feeling better! Love your videos!
We can't go back to our college classrooms again. Thanks for re-educating 🙌🏽
Nice to see you back and healthy.
Thanks friend! hope you're well too! =)
Don't worry, I am alright.
I'm so bad at picking colours. Good that there's people like you who are better at it.
Really nice video ! I love discovering unexpectedly interesting details about everyday life. It also gave me a new appreciation for a designer's work
got a treasure-like vibe from discovering this channel. I hope the algorythm gods bless you.
Thank you so much! Yay algorithm!
Very informative. Thank you.
Glad you’re feeling better Betty :) Just curious, what’s the LRV of your green wall?
It is 32 haha. Probably a bit dark for this room, but once I turn the studio lights on for recording it's pretty bright. :P
Great video! Enjoyed the analysis.
Great talk, thanks!
wow! loved this so much

Great !
Why the color blind chart at the beginning doesn't have a 100% total ?
Please make more content on interior design...! I like your videos!

You can sing chorus of Take On Me with the chords of the background music
Vanta Black absorbs 99.9998% of light, and would have an LRV of essentially 0.
Would be fun to hear your take on Vanta Black and Anish Kapoor.
I will never look at the paint isle the same again.
If an LRV of 0 would be a black hole, does that mean an LRV of 100 would basically be a mirror?

Vantablack has a 99.8 LRV apparently.
Part 1 of why I find the Sims 4 so stressful: My colour choices are horrible or extremely bland, normally both :T
Do a video on why the colour slate grey is being used everywhere nowadays and why it is an abomination.
"All you do is pick colors"
How does someone frame that as an insult? It's not like most people look at colors all day :P
Well the “insult” is even funnier when it comes to designers who only pick neutrals and shades of grey in their work. Arguably they pick no colours.
