The Color of Light
4 colors on black.

Am i crazy or are there only 3 colors in the light spectrum?

Re: The color of light

looks so nice! love it!

The light spectrum has 7 colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet.

There are however 3 primary colors: Red, Green, Blue

capedcrusader514 wrote:Am i crazy or are there only 3 colors in the light spectrum?

actually I think there are 7 (red, orange, yellow, green, blue, indigo, violet). but I chose the ones used in a few experiments I found online. here's my inspiration: http://www.colormatters.com/science_faq2.html

Re: The color of light

Gotta have the full spectrum if you want your weeds to grow to their full potential!

Re: The color of light

Hmm... blue is not a part of the Ethiopian Flag (the rasta colors) Other than that i'd buy it.

capedcrusader514 wrote:Am i crazy or are there only 3 colors in the light spectrum?

Whoa... someone's been around component video too long. There are seven colors in the visible light spectrum. These wavelengths combine their powers to create white.

Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

Now, we say that some of these are primary colors, which is where the three count may have come from, but the other colors do have distinct wavelengths. The measurement of the orange light wavelength is actually a standard measurement reference for one yard length.

Haha, it appears I've stricken quite a controversy. I'm quite aware of the other colors of light that have distinct wavelengths... a la the rainbow. This is just confusing as I assumed one would either have the three used in creating all the colors or all the colors...? Not the three with a random.

Re: The color of light

So pretty!

Re: The color of light

Nice use of negative space.

Re: The color of light

Attractive shirt!

Re: The color of light

thanks guys!!

Re: The color of light

this looks cool. =)

capedcrusader514 wrote:Am i crazy or are there only 3 colors in the light spectrum?

Actually there are only 6 colors in the spectrum. Like little Pluto, Indigo has been ruled out as a color, and no longer exists in the spectrum.

Ha Ha! That is just what I was thinking! Damn scientists...I wish they would leave our stuff alone.

Hah, I think you've been hanging around a computer too long. The 3 primary colors are red, yellow and blue.

capedcrusader514 wrote:Am i crazy or are there only 3 colors in the light spectrum?

in additive light you can use 3 colors -red, green, blue (which is what computers and tv's use. subtractive light(CMYK) is a bit different, however if you are breaking light through a prism, you will get 7 main color -red-orange-yesllow-green-bue-indigo-violet, not to mention the variety of colors in between.

I think you've all been watching Sulu on Sharp TV commercials pimping out yellow pixel technology too long.

Re: The color of light

Haha, is that a particular kind of plant? And would you include that particular kind of plant in a middle school science fair greenhouse experiment? That's the way I first read it, anyway. :P

Re: The color of light

gorgeous shirt, love the use of colors and negative space, it's a good concept that's you've implemented well

That's exactly what I thought. Sure as hell looks like a weed plant to me. And the colors fit, too.

Re: The color of light

The only shirt in this derby I would actually buy and wear. Really hope this shirt makes it to print.

I'm so sick of all the cutesy and cartoony designs that fog every single week. For once I'd love an adult-geared shirt to win.

completely unintentional... although I realize that it looks similar, it is NOT a marijuana plant. I'm actually very anti-drug.

Re: The color of light

Pretty sure the number of colours in visible light is not the important thing here. The point is that this is a very common, very basic plant biology experiment that gets repeated everywhere.

The best part is it's accurate too! Plants generally undergo photosynthesis faster under red light, thereby growing more, but more slowly under green light. The green pigments are able to absorb the wavelengths of red light, but not green light. With blue and yellow it's somewhere in between, depending on the plant.

Awesome. Totally getting this if it gets printed.

thanks for noticing the research I put into this design!

Oh geez... you're sort of right...

There are three primary colors of light, RGB (additive color).

There are also three primary colors of pigment, Red, Blue and Yellow (subtractive color). Those are the colors on the color wheel that are taught in art classes as part of color theory.

CMYK are the four ink colors used in printing.

Re: The color of light

Nooooo! It's fallen out of the fog. I really love this shirt design, not too cutesy but really great looking!

Re: The color of light

Oh no, sad to see this out of the fog too! I really like this design, simple yet obvious some thought did go into it (the different growth in different color light). Ok, I'm also a sucker for rainbows.

Yea I like the look of this one. I would actually wear it. Sometimes I think people forget weir-ability when vote for shirts.

Re: The color of light

I'd buy this if I had any money! Love it!

Actually, there would be an infinite number of "colors" in a spectrum. It's a continuum of energy of different wavelengths, and we perceive certain parts of the range to be specific colors. I'm thinking, though, that this is a good artistic way to fake the look of the whole spectrum and stay under the ink color limit imposed by Woot ;)

I could not agree more. I'm mad this shirt is no longer in the fog.

Re: The color of light

For the visual:

hankescu wrote:This isn't Science Fair-ish

Sure it is. Based on this experiment. And the instructions say "depictions of the theories explored, science fair experiments themselves, or maybe just the chemical or physical processes involved" so I'd say this fits fairly well.

All of you rambling on about how many colors on the shirt may be missing the experiment involved. It's not about the number of colors, but the growth of the plant under a certain color.

On a side note, I really enjoy this design and appreciate the research put into it.

I just realized what this reminds me of:

http://goo.gl/YzsWJ

I don't know why...it just does. =P

Re: The color of light

Gah, wish I could vote for this multiple times and get it back into the fog! I really like it and would definitely buy if it printed.

I believe the primary colors for light are different than the primary colors for pigment (as in mixing paint).
But then again, it has been about a decade since my last science class so I could be remembering incorrectly.

You're correct. The primary colors for light are Red, Green, Blue. The primary colors for pigment are Red, Yellow, Blue.
Go fig.

Amen. A lot of them look like 3rd-grader cartoons. Which is fine when they come from my own 3rd-grader, but he works for free :-)

Re: The color of light

I love this design! I'll be very sad if I can't buy it. Oh, and a few things:

1. Red, green, and blue are the primary colors of light. There are, for all practical purposes, an infinite number of colors; there are "seven" colors in the rainbow because Sir Isaac Newton liked the number seven. There are NOT only seven colors in the visible spectrum, nor are there seven primary colors.

2. No, this does not look like a cannabis plant. At all.

Re: The color of light

Wish I had voted in the Derby now



I <3 this shirt and would have bought it.

Thank you author/OP/w/e for creating this! Will CafePress or someone let you print it?

Re: The color of light

Elegant shirt! I'd buy this one. I like some of the cute ones, but I wear ones more like this. So far every one I want from shirt.woot! is in brown or olive green. I can't wear those colors -- I so do not like the zombie look.

I want this one, and several of the wood block effects, and the tree releasing birds. But this is the only one where I won't look jaundiced.

("Winters" are 40% of the population. Just because we CAN wear black doesn't mean we want an entire wardrobe of black. But lately, all the black shirts are exploding or something....)
