+EyeLean5280 We hope they have fun mixing colors! Thanks for your comment.

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.

not for paint though

for paint is impossible, the paint (cmyk) sustract the white

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.

pascoscientific Got it. Thanks

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.

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

+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].

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?

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.

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.

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
