spectrum of colors


This Time-lapse with infrared photography has been realized by Txema Ortiz.
Numerous photographs of which have been selected 6000, all using a camera converted to infrared (720Nm), was recorded during the month of December by numerous locations in Navarre (SPAIN).
The environment you want to create is to be on another planet, everything seen from the infrared camera, creating a trip to a place that has never been seen, different from what you see with the normal eye
Infrared photography is the type of photography that allows us to capture a light spectrum that is not visible to the human eye. This light spectrum is between 700 and 1200 nanometers.

Is this an ok betta tank? It’s a 10gal, heated and filtered (sponge filter rated for 20gal) with fake plants. It’s a bare bottom tank, the outside right and left and bottom sides are all painted. The lid is glass, has an uncovered 2cm strip at the back for cords. Blue photo is the nighttime light after I added some more fake plants. The lights are the finnex led.

Pls post this anonymously! Thank you!

It’s not bad at all! My only pointers are maybe see about getting rid of the paint that blocks the sides, bettas are pretty smart, pretty curious little buggers and, at least in my experience, they seem to like watching what’s around them. There’s no real need to block out the tank like if you were housing a shy snake or something. And I’m not sure about that blue light at night. I’m not positive on the light/color spectrum fish can see, but it seems pretty unnecessary to me. And if he can see it, it might mess with him a little.

Otherwise, it looks pretty great! Even the two mentioned things aren’t such a big deal and your little friend will have lots of space to explore and swim to his little heart’s content. And all of your plants look like they will be gentle on his fins. :)


And the last two, Yellow Diamond and Holly Blue Agate! Yellow was…super difficult due to her limited palette but she was a fun challenge, especially making me work in the opposite color spectrum I usually go towards for shading when it comes to yellow! Going the green direction I feel makes her seem more intimidating and unfriendly, compared to if I went to the orange side.

Also I fucking love Holly Blue, she’s a real dick and I hope we see more of her and her clicky-clack boots soon enough. Hope you guys like!

au where dean always thought that he didn’t have a soulmate because he could see all the colors in the spectrum.  They did test after test on dean because the doctors had never met a kid that was born with the full color spectrum; they thought perhaps he was just a good guesser.

cas was older than dean but they were best friends because their mothers were.  cas randomly got his full colors when he was about 2.  That had happened before - the doctors weren’t as puzzled; but it still wasn’t a common occurrence.

dean didn’t think it was particularly weird that he was born with all his colors; his best friend cas had them all too.  they were different together.

it wasn’t until they were looking at photo albums after their picturesque wedding that they find a picture of cas touching Mary’s pregnant belly at the baby shower and they knew…

there was crying on their wedding night.  happy crying.

The Science of Light, as explained by Lapis Lazuli

so i made this color edit of a screenshot of steven universe -

and got this in response

you’d expect that to kind of be the case, like, oh, her colors are darker, in low light she’d be pitch black, that’s logical, but light and color work in mysterious ways. i actually wanna talk about this because it’s a cool scientific learning experience. so @smug-torracat let’s talk about the physics of light!

here’s a side-by-side comparison of the original (left) and my edit (right), with lapis in white sunlight. white light is a mixture of the entirety of the light spectrum and has every color. so lapis here absorbs all the colors in white light except for blue, which she reflects thus making her blue to our eyes.

the bulb is the sun, the filter is lapis’s skin/dress/hair, the square on the right is our eyes.

now let’s look at a screenshot of lapis in mirror gem/ocean gem.

in this scene, it’s pretty dark, and everything has a vaguely dark blue filter over everything. we can assume that this scene takes place in surroundings with a mixture of low blue light and low white light.

this is my best attempt at recreating the light conditions in the scene. here, lapis is standing in both low blue and low white light. it’s not perfect, but you can see that the lapis on the right has colors extremely similar to the lapis in the mirror gem/ocean gem screenshot.

okay, why isn’t she black? white light + blue light + blue filter = blue appearance.

if the surroundings (the bulb) are bathing lapis (the blue filter) in blue light, then she’s absorbing nothing. blue objects can’t absorb blue light, so the blue light reflects and we (the square on the right) see nothing but more blue.

black is the absence of any color in the light spectrum. in order for us to see black, all light from an object would need to be absorbed. so for lapis to appear black, she would need to be in either red or green light.

if she’s in red light, there’s no blue light to reflect off of her clothes and back to our eyes. blue objects absorb all red light, making the object appear to us as completely black.

you can see how her hair and triangles on her outfit on the right appear almost entirely black, and she’s in mostly shades of gray.

so there you have it - my recolored lapis matches mirror gem/ocean gem lapis without a hitch. yay, colors!


Pale yellow and orange colors of the midnight sun, Iceland. The whole spectrum seems here - orange, red, green, violet.
