Designer Jinsun Park from Korea has come out with a simple tool called Color Picker. Place the pen against an object and press the scan button, the color will be detected by the color sensor and the RGB cartridges in the pen will mixed the required inks to create the target color.




R,G,B ink cartridges? sounds like someone hasn’t done their color theory homework.
Sorry, this won’t work. The RGB values that the sensor picks up would have to be converted to a CMYK palette to mix cyan, magenta, yellow, and black inks… not red, green, and blue inks.
Visual light (RGB) is “additive”. By adding light to achieve a desired shade of color. Add all three colors and you get white.
Printed (CMYK) is “subtractive” — Light is absorbed and some is reflected in a particular wavelength corresponding to the desired hue. Combine all of these inks and you should get black.
This pen is cool idea, but it has not been thought through and obviously only exists in the conceptual stage.
Though limited in ability to reproduce hues (particularly yellows), subtractive RGB inks are possible.

Uh RGB will not work?
Wow someone tell the TV makers of that. Colour televisions have been working on RGB pixels since there has been colour television. Now that it has been discovered not to work all colour TV’s will change to black and white!
The reason RGB works for TVs and Monitors is because those devices are mixing wavelengths of light, as they are capable of emitting light. Obviously inks are not capable of emitting light. Therefore they work on the concept of absorbing certain wavelengths and reflecting others. It is called subtractive color theory. Please brush up on it before you attempt to condescend others more knowledgeable than yourself.
This concept has been kicking around the web for at least 6 months…
Uh Ha Will to work. look she’s drawing with it. see it works.
XD
lol, trevor got pwnd!
A properly adjusted colour television should show a good blacl & white picture if the colour or saturation is turned down or a b&w show is on. If not the tv needs work.
Another fact: you can not get a true orange with RGB. It may look like it but it isn’t possible.
Still the pen is a great idea.
You’re all wrong! The pen actually uses Hot Pink, Eggshell and Mauve! Geez – don’t any of you know anything about color? The pen is fabulous darlings – simply fabulous… ha ha ha
Brian- Just because you -do- know doesn’t give you any more right to be a condescending twat.
Actually, if you do know, you are more right to be a condescending twat than if you don’t know. Especially when the person receiving your condescension is obviously a pratt. If Trevor had read the second post, where it was explained why RGB wouldn’t work (apologies meddington) -in this case- (so not necessarily an electronic display system anyway), he wouldn’t have made such an ill-informed comment, and not received the appropriate level of polite condescension, for which we must thank Brian.
That will be all.
Photoshopped, I can tell because it has pixels.
that would be really cool
Of course it was shopped… they messed with the color of the cartridges. It should be Cyan, Magenta, and Yellow. O_o
Additive color: color created by superimposing light rays. Superimposing the three primary color lights- red, blue, and green- produces white.The secondaries are cyan, yellow, and magenta.
Subtractive color: The sensation of color that is produced when wavelengths of light are reflected back to the viewer after all the wavelengths have been absorbed.
I would go into more detail on how this works for the lamen but I find this pointless on the internet. Anyways, the designer should have known better, unless he is self trained and knows nothing about traditional art. If ink mixes anything like paint does then the colors (hues) should be the primary colors…
Primary colors: the preliminary hues that cannot be broken down or reduced into component colors. The basic hues of any color system that in theory may be used to mix all the other colors.
So the pen should contain hues or colors: Yellow, Red, and Blue. Since mixing all three doesn’t create a perfect black, a black ink may also be necessary. As for white, leave the canvas blank since white ink probably doesn’t cover any other hue properly.
Argue my point, but my reference (something that doesn’t exist in non-logical internet jabber) is:

whoa… art school is paying off.
well my 9 years old daughter is waiting for it….so be quick..and let me know from where to get it….:)
