Totally Lighting Challenged -- HELP!

[indiginess]

hahhahhahaha

ok that really made sense to me. but then again i was told that the stars were alive once, and that made sense too.

violet and red orange are one set, blue and red are another.

they happen at basically the same time.

plants need those light waves to make the electrons dance.

we see green.

i think you mentioned something about color order.?..

:joe:

Ah, I think? But violet and red orange are not related to one another. How can they be of the same set?

You need blue and red to make violet, so yah, but red orange -- where is the yellow? You can't have red-orange without yellow.

plants need those light waves to make the electrons dance.

We see green because they absorb all other colors.

Ie: (I assume you know this, this is for anyone else reading this) put simply --if a fish is totally red (I mean TOTALLY) then it absorbs all colors but red, so all we see is red.

i think you mentioned something about color order.?..

The color order is how they run on a color wheel. The "primary and secondary" colors***, in order: red, violet, blue, green, yellow, orange -->red

On a proper Color Bias Wheel, there is no red, yellow, or blue, but warm or cool variations of each: Quinacridone Violet, Violet, Ultramarine Blue, Cerulean Blue, Green, Lemon Yellow, Cadimium Yellow, Orange, Cadminium Red

In English: red-violet, violet, blue-violet, blue-green, green, yellow-green, yellow-red, orange, red-yellow. In other words, you won't find a tube of quality oil or acrylic paint that just says "blue". The color "blue" just doesn't exist.

*** without going into more great detail, there really are no such things as "primary" or "secondary" colors. If anyone wants detail, ask, otherwise I'm not going to bore everyone to death

ANYHOW . . . :dance2:

If the plant uses all colors but green and needs violet to produce the green, then it stands to reason that it needs all forms of violet: red-violet, violet and blue-violet. No?

That's why I asked about red-leaved plants. We see red, not green, so do they need a different light waves?

Blah,

in the light spectrum, there is no circle.

X-rays, UV, visible light (violet- red), infrared, microwaves

there is more on both ends.

the length of wave increases from left to right.

i should have been much more specific, i'm sorry

there are two main components in photosynthentic light abosorbtion, what chlorophyll a needs, and what chlorophyll b needs.

chlorophyll a has the highest wave absorbtion in the violet range and the orange range.

chlorophyll b has the highest wave abosrbtion in the blue-violet range and the red-orange range.

a, then b.... seperated by VERY little time... it doesn't matter, it happens so fast

( just about submitted and reread, this is where i make the stretch)

but the colors actually neutral out, from a color wheel standpoint, i guess...or create a color that would be opposite green when mixed

but green is NOT absorbed by A or B

we see green

sry that got so confusing...

Marineandreef.com has the Orbit series cheaper than anywhere on the net. I bought mine there (and of course I don't need anymore). I'm tearing it apart to reuse on my big tank now .

I am SO glad you sent me there. Not because of the prices (which look great, btw), but because of this:

(*Length and width includes power cord and switches. The length of the housing is 1/2" less. If in a tight space, please keep in mind that the fan input and output are on the ends of the housing. D0 NOT put this light under a canopy.)​

​

This true? I know sometimes places may post something like this to absolve themselves of anything in case there is a problem.

Geez. I was gonna move my python into a smaller cage and use the stand and canopy for one of my tanks. I probably still can, just need to get hubby to add some more fans and ventalation to the canopy or light housing.

Has anyone done this?

Now that cool. Trying to visualize endless color -- if we could see it all. Ooooooooooooooooooooooooooh.

Nada to be sorry about

chlorophyll a has the highest wave absorbtion in the violet range and the orange range.

chlorophyll b has the highest wave abosrbtion in the blue-violet range and the red-orange range.

AH! Okay, now I understand. It's unrelated -- separate chlorophylls = separate needs

( just about submitted and reread, this is where i make the stretch)

but green is NOT absorbed by A or B

You said, "or create a color that would be opposite green when mixed" --

If you took all of the ranges the chlorophyll use out: violet range, orange range, blue-violet, and the red-orange, what you have LEFT is:

red-violet, blue-green, green, yellow-green, yellow-red

AND if you mix the two that are not equal to green: red-violet and yellow-red you WILL get a neutral or crap color. Remember as a kid and you mixed red, blue and yellow and got muddy brown? All those colors are in those two leftovers. So perhaps:

we see green

Now, does that make sense against what you meant? If not, heck, no matter, I had fun applying color stuff to this I need to learn more about this stuff. It's pretty cool.

i'm no expert on color mixing, and i'm sure you are right. like i said, it was a stretch. guess theres no point in adding something like to future discussions. i added the mixing aspect to try to aid in understanding, since you obviously know your color (ran across a reference that you paint). i think it added more confusion than anything else. its amazing the effect of little sleep and too much reading can have on the mind.

man, this site gets some serious traffic. 24 hours later and i had to go through 200+ threads to track this down.

glad i could help somewhat.

yeah light is just fasciinating. it behaves as a particle stream and a wave. really neat stuff.
