Concept Art Thread

Correct, thermoplasts don't exist outside of our game concept- I imagine them to be black, maybe fuzzy, fibrous organelles.

I'd imagined them red/orange and a little brown, with something similiar to a heater...

I'm open to see whatever comes up.

I think Chloroplasts should be the same color as the opposite of the sunlight,

On earth chloroplasts are green, this is because at green they get the most energy(absorb the most light in there situation)
however if our sun was red, I think chloroplasts would be black because that way they get the most energy because red is at the end of the spectrum. So they need all the energy they can get.

Can we do like in minecraft then, where the grasses texture is actually greyscale, and then can get many different colours depending in the biome.
That we uses greyscale texture for it, wich we then can add colour to depending on the sun, in game?

Hmmmm... I think so.

What's you gonna see on your gui? (ATP,nutrients,main menu button, chat window,map etc.)

Good idea- we already have info on the different colors we should use depending on light.

Anyhow, this can be used as a chlorophyll guide because the Transmitted light (i believe you mean reflected light) is the leaf's visible color, and the Absorbed Light is the wavelengths that it wants to absorb. If leaves are maximized to the dominant color being put out of their star, or something pretty close, we have chlorophyll sorted with this handy chart.
Notice that multiple pigmentations are possible - on earth, plum-colored (purple, according to my chem book) leaves are not as common as green leaves, but we definitely have a range of yellow green through blue green leaves, which match up well with a star primarily putting out yellow light. They're enough out of phase to prevent overheating.

Star Color: Red Leaf Absorbtions: Blue Violet, violet, purple Leaf Color Orange, Yellow orange, yellow
Star Color: Orange Leaf Absorbtions: Violet, purple, red Leaf Color: yellow orange, yellow, yellow green
Star Color: Yellow Orange Leaf Absorbtions: Purple, red, Orange Leaf Color: yellow, yellow-green, green
Star Color: Yellow, leaf Absorbtions: Red, orange- yellow orange, purple leaf coloryellow green, green, blue green
Star Color: Yellow Green, (doesn't exist)Leaf Absorbtions: Red, Orange, Yellow, Leaf color: green, blue green, blue
Star Color: Green, (doesn't exist) Leaf Absorbtions: Orange, Yellow, Yellow Green, Leaf color: Blue green, blue, blue violet
Star Color: Green blue, (doesn't exist) Leaf Absorbtions: Yellow, Yellow Green, Green Leaf Color: Blue, blue violet, Purple
Star Color: Blue, Leaf Absorbtions: Yellow Green, Green, Blue Green, Leaf Color: Blue Violet, Violet, Purple, maybe some red
Star Color: blue Violet Leaf Absorbtions: Green, Blue Green, Blue Leaf Color: Violet, Purple, Red

Actually, i believe that plants on earth are mostly green because chlorophil (which is green) has other few properties that makes it way better than any other known substance.You can see a nice video about why are leafs green on
youtube. It is titled "why are leafs green", by minuteearth.

Anyway, no matter the type of sun, the best colour to soak up energy is always black. On every situation. But i agree that plants of diferent colour would be nice.

((Disclaimer, it's been a couple years since I've had a discussion on this. Feel free to correct me if I'm talking out of my rear end here))

There is a thing as too much energy, though. Black chlorophyll retains heat as well, and there's a good chance that such a plant (under our sun) would absorb too much heat, potentially throwing off all number of chemical processes. The reason that plants on Earth are green is that they actually have two types of chlorophyll, one better suited to absorbing high-energy, blue light, and the other absorbing light towards the red end of the spectrum, which has less energy, but is more abundant in our star's spectrum. Over the course of evolution, they met roughly in the middle at reflecting green light, at which point the gathered energy was pretty much sufficient for whatever the plant is doing, and thus there was little selective pressure to produce much more of one or the other.

(Incidentally, this is why leaves turn red in the fall: the red-absorbing chlorophyll, (which if I remember correctly, decays faster) is no longer produced by the plant, leaving the blue-absorbing chlorophyll behind, which in turn reflects shades of yellow and red.)

What this means is we also have to take the energy output of the star into account. Dimmer stars (particularly red ones, which emit lower-energy radiation,) would prompt darker chlorophyll, whereas brighter ones (in particular blue ones) may even need to have plants evolve reflectivity at certain spectrum lengths to prevent too much energy being gathered/being affected by the increased level of ionizing radiation (I'm mostly thinking some sort of natural sunblock here against UV.) Then again, I'm uncertain whether we're simulating ionizing radiation, so that last part could be a non-issue.

If we were to generate stars using presets (to fall in line with observed patterns) we could simply add preferred chlorophyll colors to the preset. See here for more on that.

(Sorry for all the parentheses)

Extrasolar pretty much sums it up.

Here's some concept art I drew some time ago for a fungi based humanoid:

Spoiler:

Good info Extrasolar, so its definite, we will have different colored chlorophyll.

Possibly. Every aerobic photosynthesizer on Earth uses a type of chlorophyll called Chlorophyll a, which absorbs mostly reddish light, but some blue, reflecting back mainly green. The wide variation in color of photosynthesizers that we see on Earth comes from the use of other, accessory pigments that absorb other wavelengths. These can modify the base color greatly, but they are doing just that, modifying it.

The question is if this universality is just because of the sun's spectrum, or would it also be widespread on other planets with other stellar spectrums?

(Ultimately, the only difference we'll see is whether bright blue, violet, or red plants are possible, particularly red.)

Well, I need to know I will be implementing it in my prototype. ( I will simply randomize the star and have pigments maybe evolve.)

I feel it's not my say, but I suggest we shouldn't worry too much about the exact pigments we're using, since it really won't make that much difference past cellular. I say go with the previous suggestion of having the assets for chloroplasts, etc. be greyscale, so a variable color overlay can be added in later.

I actually saw a Bungie presentation on particle effects, and they used the exact same image for every single gunshot in Halo 3. They used a grayscale .png texture, and then stored gradients that lent their color to the image depending on the gray value.

Brilliant, Bungie's developers are geniuses. This seems like a good, manipulable way to add some variety to ordinarily boring and uniform plant colors and should fit in with the ideas presented here.

I want to add a drawing i am 14 but i have the drawing skill of a six year old can i still post a picture?

Sure you can!

In a surprising turn of events, I have created some Concept Art! It's pretty basic, but it's a start. Tell me what you think!

Spoiler:

(Made with SpaceEngine + GIMP)

Holy belgium... Its awesome!

that's awesome Jacob!

That is amazing Jacob! What are those spark looking things flying out of the planet?

It looks breathtaking. I would use this as promotional art, or as a background for a menu or game design document.

Thank you so much guys! Nick, it's actually a cluster nebula... I spent so long trying to find a good cluster nebula

Wow it looks really nice.
