S'plain this one Lucy
I have two fused test pieces. The first is a combination of BE 1120 (yellow transparent) and BE 1401 (crystal clear). The second is a combination BE 1114 (BE royal blue transparent) and BE 1401 (crystal clear). In both pieces the clear acts to "thin out" the color density.
When I hold the two pieces (stacked) up to the light as expected there's lots of green light.
What I didn't expect -- and is clearly there -- are areas of deep redish/orange.
I went back and checked Mouse Paint*. According to it, there shouldn't be any red tones.
Wuz up?

Magic? Could it be magic?
I had something similar happen about 9 years ago. I made a bowl by stacking sheets of transparent red, yellow and orange together. I was trying to make persimmon color that way. Much to my surprise, from the top, the bowl looked green. From underneath it was a deep red. Where did the green come from? Magic. It must be magic.

2 make the colour the glass probably got a lot of other colours inPaul Tarlow wrote:I have two fused test pieces.

Also
U might look at the way a tv works
Cyan magenta + other
A bit weird these colours comming from the overlaps
Also a few glass colours make a different colour in transmited light rather than reflected
Like the Lysergis cup in the V+A or British Museum

Re: S'plain this one Lucy
What color light are you looking at? Is the light full sun spectrum? You're just bending some light that bullseye can't predict for you. I'm not surprised. I'm not even going to pull out my sample set and check your colors out (until later today). So is this mouse book any good?Paul Tarlow wrote: clip

Its a kids book for teaching about colors -- and its wonderful. Was one of my kids favorites when they were littler people.Don Burt wrote:So is this mouse book any good?

Re: S'plain this one Lucy
I think we're getting close with this. I'd bet some wavelength is being reflected in the combination that you wouldn't expect looking at the individual colors. You know, something about the whole not being equal to the sum of the components or something like that.Don Burt wrote: What color light are you looking at? Is the light full sun spectrum?

1) The effect was the same under both incandescent and fluorescent lights
2) The effect appeared when the two pieces were held together. Once fused, the red is gone.
There may be other variables that I'm missing -- going to try and reproduce this.

I Googled 'light refraction' and came up with many. This is just one.

This is an interesting conversation and made me think of old opalescent glass. It's just white, but in certain lights you can see glints of orange and reds and purples. Like magic.

I fooled around with those colors in my sample set and couldn't get the red to appear. I only had one piece of clear 1140 though.Paul Tarlow wrote: Add this to the mystery:

Not true. I even showed it to my 6 foot rabbit friend Harvey and he sees it too!Don Burt wrote:I think Paul's just hallucinating.
