Default Seeking Online Additive Color Calculator

Has anyone seen an online additive color calculator? I need one for light. I found Osram offers a free LED color calculator, but it won't run on my Apple OS version. Can anyone do me a favor and run this program for me:

https://www.osram-americas.com/en-us...alculator.aspx

What I need to know is what shade of color 1.5 watts of 660nm, 1 watt 561nm and 5 watts of 532nm produce when combined.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

I downloaded the program for you, but it doesn't allow an addition of two green bands, 532 and 561. Green is between 513 and 570nm. I am also getting to grips of the program, but it does seem to be lessening the extent of the green.

OK, thank you for trying my friend. I just wanted to get an idea of the shade of color the eye laser I have would produce if all three lasers were on at the same time.

You want a copy of "Chroma", although I'm not sure if it runs on Mac? Anyone? I have a copy of it somewhere, but in a .exe format I think.

You're welcome Alaskan. I was looking for Chroma not so long ago. If anyone has a copy, please share.

I should still have a copy of it somewhere, I'll need to check later tonight. I had it installed on one of my VMs, which was on a host that had a drive failure, hopefully I copied it onto the file server before that happened...

I'd like to see the result of three colors added together, don't know if these programs allow that many to be calculated together.

I did try making my own using Excel, but it is very difficult getting the accuracy right with three whilst capping out at 255. I'll have to give it another go sometime.
