Have you ever dream of having like a Photoshop’s eyedropper tool in a real life, if so your dream came to be true with the new ‘Color Picker Pen’ concept designed by Korean designer Jinsu Park.
The Color Picker pen works just like the eyedropper tool in Photoshop. It allows user to scan any color from environment and instantly use it for drawing.
The sensor detects the color and matches it to the color display. The color is detected by RGB color sensor inside the pen, after detection RGB (Red, Green and Blue) cartridge mixed colors together to create a detected color.
Get one and let’s make draw fun and easy with a realistic color picker!


This pen could only work in CMYK for the simple reason, that beyond colour gamut, RGB is a subtractive colour system where you start with black and then add light (colour), that is why screens fuction using RGB. CMYK is an additive system, you start with white (paper) and add ink (colour).
I think samorost has a point, forget actual ink. I would think the mechanism to mix and match ink correctly on the fly would be silly, and if it was mastered would require way to much development effort.
Its a clever concept, you will need a USB interface and inkjet technology and yes a colorimeter of some sort with a built in standard light source all scrunched into a pen body…I would say its a few years off but not impossible with a great deal of engineering and cash. But wait, think about it.. who needs this? when you can do it with a computer and a printer, why regress? JR
The modified version of this concept, not rgb, would be great, but the version shown here is pointless, it is like creating a rube Goldberg machine to press a button. Even a more capable version with all colors available would still be next to worthless as nearly everyone will only ever need black, blue or red. Artists may have a greater use for this however I can’t see how this would replace an artists current media.
I don’t think it’d have to require every color ever. Just the color wheel, and then the colors of course, would mix and make that color, just as every color is made. I think this is an awesome idea, I wonder how much it would cost.
Actually, neither RGB or CMYK cover anywhere near the visible color gamut of a human, let alone a cat. It would need to be CMYK only because the combinations of R G and B only really apply to light. When you are adding inks together it is a whole different process. And coloring anything but white paper would throw the whole thing of and further limit your option. Other than the total pain it would be to calibrate properly, it seems like a really great idea! Ask a printer. Oh wait, that’s me. :)

December 29, 2011 @ 4:27 pmTo detect the color from the environment it’s necessary to have the RGB sensor, because it’s light mixing and we can see colours from the environment because color itself is light reflected from the object to our eyes, but it’s not the same for print… the pen should have a color processor to translate the RGB information into CMYK and 4 cartridges, Cyan, Magenta, Yellow and Black to make the printing possible, but it’s a cool idea.
