Very nice! A very cool gadget.The first part of the video also explains how a television picture tube achieved the color yellow, as the primary color "guns" of the tube are red, blue and green. Great video!
As soon as my students saw this video, they begged me to buy this for the class!

We hope they have fun mixing colors! Thanks for your comment.
What color do you see when you mix yellow light and magenta light (secondary colors)? Will it be pale orange?
That mixture looks somewhere between peach and pink to me. Since yellow is red + green and magenta is red + blue, the mixture you propose is one part green + one part blue + two parts red. I tested the result by setting the Color Mixer's blue and green brightnesses to about half, while leaving the red at full strength. The resulting mix in the center appeared pinkish to my eyes. That seems reasonable, since equal parts red, green, and blue would appear white and the extra part red light would tint that white color toward red.
Thanks for your question.
Edmunds could take some pointers on presentation skills from this 👀. Love this.
So now I know what colors make white! 😊
not for paint though
for paint is impossible, the paint (cmyk) sustract the white
I will tell my class about this. AWSOME!
an excellent education
I need to buy this accesory... but I can't find it on amazon.....
Inside the US, you can purchase it from the PASCO website at www.pasco.com/go?os-8496. Outside the US, you can find your local PASCO reseller at www.pasco.com/support. Thanks for your interest.
Can we mix yellow light and red light to produce orange light !?
See if you can spot how to create orange light in the video.
Hint: Starting at about 1:20, look for the presenter changing the relative intensities of the mixture of red and green light.

Got it. Thanks
This is really interesting great job!
Good work
Very nice!!
we take this in school today and I still don't believe it!! you're telling me if i mix light blue with yellow i'll get white!!!!!!
Please explain the difference between the two yellow reflective cards.
Card 17 uses a standard yellow pigment, while card 18 uses a fluorescent yellow pigment, which you can see fluorescing in blue light at [5:26].
@@pascoscientific
Does that mean that one card is a pure 580nm yellow and the other card is a combined red/green type yellow?
What if the object is red but blue and green lights goes in so white is the results?
This is so cool.
Thank you..
How do you mix brown colors with this kit?
Brown is usually described as a low-brightness orange. So you might try first getting orange like you see at [1:28] with the mix of red and green lights and then turning down the intensity of both.
Eso es bueno ..but u should use a dark room for better results
What wavelength of light were used?
You'll find more information on the wavelengths of the mixer's red, green, and blue LEDs in the product manual at pasco.com/product/OS-8496. Thanks.
@@pascoscientific thanks for replying sir, I want to order it.but I am unable to buy.there is no option there to buy.
Thank you

Looks like the Apple little thing for filters
Thanks alot
Hi, Thanks for the video; very clear. What I don't get is why don't we get yellow when mixing red and green paint or markers, etc? Thank you.
To learn more about why mixing paint colors is different from mixing light colors of light, try investigating the differences between "subtractive" or "pigment" color mixing and "additive" or "light" color mixing, which is shown in this video.
Use smy colour model without k.
Because s+m+y = k = black
How this cost?

I would like to buy a Pasco color mixer. But I am not a Teacher ....I am just a Man that loves Physicwould you know where I can get one ..Thank you
Great to hear from a fellow lover of physics. While teachers are PASCO's primary audience, we do also sell to interested members of the public. Just contact your local PASCO representative: www.pasco.com/support/customer/find-your-rep/index.cfm.
Amazing!
oh thanks for unique demonstration
Cool
wow
what color is cyan
+Saraia Cottman
Cyan is the mix of blue light and green light that you can see being created in the video starting at about [2:04].
This ignores indigo, that pesky seventh color!
Also, I was wishing she would explain the two different yellows.
Indigo is just a mix of blue and violet. And violet is already a mix of blue and magenta. So indigo is just derivative, crimson, vermillion, amber, cerulean etc
Here's the thing. The color wheel is based on the three colors yours eyes actually can distinguish: red green and blue, and then the secondary colors you get by mixing them: cyan, magenta(not really purple), and yellow. Your eyes can see more frequencies but they all get filtered into only three color sensors in your eyes so your eyes figure out colors from those three. That's why you see white from only those three colors despite natural white light containing all colors of the rainbow.
Magenta actually isn't an extisting visible frequency of light but only exists in your mind when it combines blue and red frequencies coming from something. Let me explain.
The visible light only goes from red, the lowest frequency and to violet, the highest frequency. Magenta exists between red and violet so it can't be both high frequency and low frequency at the same time. It's because it's not a single wave length but the color that exists in your brain when you see both red and blue .
So going back to the rainbow, the rainbow was not designed around the tri-color based wheel but by all the visible light frequencies from top to bottom. Also the number of colors in the rainbow isn't strictly scientifically split in any way but more which ones are easy to distinguish. Indigos inclusion seems a bit odd because you can barely see it as a separate color but there is a theory that its included because back in the day of isaac newton(who chose these colors) indigo used to mean "deep blue" closer to what we know blue to be today and "blue" probably actually referred to what we know as cyan today.
One more thing to clear up. The red yellow blue color wheel taught in schools is not scientifically accurate as primary colors . The correct one is cyan, magenta, and yellow.It actually makes the whole system make sense.
Mixing paint the secondary colors then become red, green and blue, which you'll notice work precisely opposite when mixing light. The primaries and secondaries match eachother in opposite color mixing methods.
Thanks for coming to my ted talk.
Green Light Red Light...MWHAHAHAHA
Red and green make brown
That is with paint. When you mix paint you are decreasing the number of colors that can bounce back to your eyes. Paint sucks up some colors so if you mix to many colors you get black. But light doesn't work that way. If gets brighter rather than darker when you mix it.
this is cool but so old. i like this so yeah
