It's very impressive what your app can do with a rock or a color. This is how your brain does it. Key word shine and glitter etc. Members 1.5k Location:Sparks , Nevada Gender:Not Telling Posted April 12, 2010 Thought some might be interested Article by Betty Edwards, Drawing on the Right Side of the Brain, p231 Placing color in the brain Given sufficient light to percieve colors, scientists also tell us that the brain's reaction to colors seem to depend on the differences in thinking modes of the various sections of the brain. Very bright, intense colors (and colors that shine and glitter) draw a response from the so-called "primitive" brain, the limbic systems. This response is an emotional one, perhaps connected to our biological heritage of color as communication. For example, many people say, "When I get mad, I see red!" The inverse of this exclamation perhaps describes the situation whereby an intense red elicits an emotional, aggresive response. The main role of L-mode, generally located in the left hemisphere, is to tag colors with names and attributed, such as "bright blue," "lemon yellow," or "burnt umber," and to translate into words our emotional reactions to colors. Additionally, L-mode is specialized for designating sequenced steps in mixing colors- for example, "to mix orange, add yellow to red," or "to darken blue, add black." The right hemisphere (or R-mode) is specialized for the perception of relationships of hues, particularly for subtle linkages of one hue to another. R-mode is biased toward discovering patterns of coherence, specifically toward combinations of hues that balance opposites- for example, red/green, blue/orange, dark/light, dull/bright. In his 1976 essay "The Dialectics of Color," Dr. Peter Smith states: "Since the right hemisphere has a strong interest in the way things fit together to form a closed system, it may be said to be a decisive factor in the esthetic response." This closed system may be what artists speak of as unified, harmonious color- that is, color in relationship that are locked into balance. Perhaps R-mode recognizes the satisfying wholeness of properly unified color and reacts with a pleasurable sence of "Yes. That's it. That's right." The converse is also tru: R-mode recognized unbalanced or disunified color arrangements and perhaps longs for unity and the missing parts of the closed system. An individual may experiance this longing as vague dislike- a sence that something is missing or out of place. R-mode has another important role in color: seeing which combination of colors has produced a particular color. Given a range of grays, for example, R-mode sees which one is warmed with red, which is cooled with blue. Hope you enjoy,from a favorite Art book. Bo

Thanks William, you can call me Bo

Thanks Steph ,I'm glad you like them, one more time

Really,what happened to my cat ?

Thanks Chad for the info. I learned alot about snotties. As Ron said snotties were sold in different colors,etc.,as long as they looked snottie. Times change a better definition is needed. But if I ever do find one of these things I will want it to glow like yours. BO

Thoughts ? 5/8" opaque

Thanks again Ron. I really had no idea on these ,I will put with the Alley's

I posted the above marbles io the wrong thread,should have been Masters. SORRY

I'm not even gonna guess. Marble on the left , dark transparent red base glass. The marble on the right is opaque. Both 5/8" range. Thanks

have a great day

And this one

Great masters everyone. Here are a couple of mine

A favorite of mine

Hello Ron, Thanks for chiming in here , I appreciate your input. And yes I understand my marble is not a snottie ,don't think I ever claimed it was. My interest now is the flourescent quality of Chads marble,for ID purposes.If Chads marble reacts under UV as he says, then do all snotties react under UV ? And what color flourescent ? Green?,orange? both colors like mine? This has been a good learning thread ...Thanks Ron for taking time to comment, BO

Chad you said "Pictured is mine, yes !! the opaque striations do fluoresce under uv." Just wondering what color ? I think were I went wrong was I started with bad pics. Here's one last pic, I assure you the base is clear

Hi Chad my marble has a clear base glass not yellow. And your marble does it have two colors of flourescence like mine? Hi Chad my marble has a clear base glass not yellow. And your marble, does it have two colors of flourescence like mine? I don't think your marble is like mine at all, but I could be wrong. So your saying the only snottie must be CAC and brown as pictured? Seems we had this discussion many years ago and more colors were included. I not an expert just a collector

OK...I don't have one of those, trying to picture that combo.Thanks

Better pic's colors are closer to correct.

A goog snotty should have some interior structure

These appear to be Peltier black or very dark purple cat-eyes,they can be found.

Hello, I don't know much about MK but I have a few. MK Panda ?

One more, Great marbles everyone!! Alley?
