color
Color (American English), or colour (Commonwealth English), is the characteristic of human visual perception described through color categories, with names such as red, orange, yellow, green, blue, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the visible spectrum. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc.
By defining a color space, colors can be identified numerically by coordinates, which in 1931 were also named in global agreement with internationally agreed color names like mentioned above (red, orange, etc.) by the International Commission on Illumination. The RGB color space for instance is a color space corresponding to human trichromacy and to the three cone cell types that respond to three bands of light: long wavelengths, peaking near 564–580 nm (red); medium-wavelength, peaking near 534–545 nm (green); and short-wavelength light, near 420–440 nm (blue). There may also be more than three color dimensions in other color spaces, such as in the CMYK color model, wherein one of the dimensions relates to a color's colorfulness).
The photo-receptivity of the "eyes" of other species also varies considerably from that of humans and so results in correspondingly different color perceptions that cannot readily be compared to one another. Honeybees and bumblebees for instance have trichromatic color vision sensitive to ultraviolet but is insensitive to red. Papilio butterflies possess six types of photoreceptors and may have pentachromatic vision. The most complex color vision system in the animal kingdom has been found in stomatopods (such as the mantis shrimp) with up to 12 spectral receptor types thought to work as multiple dichromatic units.The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the study of the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what is commonly referred to simply as light).
This is an unopened Simmons Whitetail 3-9x40mm Rifle Scope. These are great scopes I typically use these scopes for rifles I beat the crap out of and they hold. They sell for $133.99 at optics planet which is one of the better optics dealers with some of the best prices. Matte black

Bought this from another member last year thinking it would be perfect for my “end of the world rifle” but red dots work better for my eyes.
Has the red cross hair 5.56 reticle, tritium nice and bright, not sure what year it was made. Comes with a matching ARMS qd mount and RMR mount with back...
Picked up 2 yards of this 500D fabric, the ebay seller photos showed a more green shade than what I got, so it isn't gonna be used for tactical gear.. but it's useful for a backpack that doesn't look tactical.

Has anyone else attempted to do a color fill on their Springfield Armory Hellcat?
I did and it didn't work too well. I also have a Springfield Armory XD45 that I did the color fill on a while back and used the same process for the Hellcat.
I used nail polish (enamel paint) and fingernail polish...
Henry 30/30 new. Has Skinner Alaskan Peep sights on it. Will also come with 120 rounds of Hornady 150gr FTX Lever Evolution. Rifle is beautiful, and has 20” Octagon barrel. Just a perfect deer setup. Paid over $1,200 for everything.
Let me know if you have any questions!

After years of research and experimentation I finally mastered the art of Color Case Brass!
Well, not really ! I was pre cleaning the brass .357 with some aluminum 9mm in my tumbler with dawn, apple cider vinegar and spent primers as media (yea they work great as expendable media) and the...
this was for my madland aero builders kit but decided to run the full rail version instead since all my eotech stuff takes up so much rail space. These go for 175 plus shipping without the madland custom cerakote so I feel my price is very fair, however if you feel differently shoot me a PM with...
