yellow is 255 255 0 255
bold number is opacity

Thanks!

technically yellow can be any combination of RGBA values as long as R and G are both within 50% of the other and greater than B, with some non-zero value for A

I really like this site when picking out colors for hud elements!

You probably learned in elementary school that there are three primary colors: yellow, red, blue. What they didn't tell you was that these colors are only the primary colors for a particular "color model" called the RYB model(after the colors). This model is further classified as subtractive, meaning that the color that you see is whatever is not absorbed (and thus reflected). For example, yellow looks yellow because red and blue are removed from the light.

It actually turns out that this model isn't the optimal subtractive color model out there, the best is called CMY[K] after the colors cyan, magenta, yellow, (and black). If you noticed, more recent printers have started to use CMY as their color cartridges over RYB for this reason.

On the other end of the spectrum, there are additive color models, where the light you see is a pure combination of colors, no fancy reflection tomfoolery here. There are also primary colors for these sets of models, with the most common being red, green, and blue, known together as RGB. Additive color models are the much more physically interesting ones, since it is easier to create objects that emit light of a certain color on demand, but fairly difficult to create objects that can be controlled to subtract light on demand. As a result, the computer world uses the additive RGB color model to produce colors. In many applications there is a fourth value that is associated with this model called alpha (abbreviated as A), which controls how not see through an object is. No Alpha, can see right through it, Max alpha, you cannot see through it.

Since additive colors were probably never taught to you in elementary school, I'll give a quick overview. As it turns out the three secondary colors of the additive RGB model are YCM (the primary colors of the subtractive model CMY) in that order. For example, Max red + Max green = yellow. If you want crazier colors than these then your best bet in the future is just to google "COLORNAME rgb", or if you want a list of colors just search "rgb colors". My first result is here.

Pretty much every application that asks for a RGB[A] color expects individual values ranging from 0-255. Sometimes you will see the value in hexadecimal which range from 00-FF and are prefixed by a #.

yo he just wants to make his crosshair yellow guys

I WANT TO KNOW EVERYTHING THERE IS KNOW TO KNOW ABOUT COLOR THEORY AND LGHT WAVELENGTHS DAMNIT

i learned about this in my web development class

but what is color, really? can we even be sure that the light picked up by our eyes is accurate to reality, or if it is even real at all?

ha, "yellow." only fools would blindly believe in such a human-defined construct!

Actually ours eyes are a little strange when it comes to seeing light, and we do not see perfectly at all.

You can overload your cones (what see colors) to trick your brain into seeing "incorrect" colors as well as create colors that your cones aren't very good at seeing (which then requires your brain to interpret what colors you are viewing.)

What your eyes see in relation to the physical value of a lights wavelength/frequency is a real problem when capturing pictures and trying to make things as life-like as possible. Look at any astronomy picture and pretty much every one has been taken in three non-rgb colors and then masked onto r,g,and b to make it appear colored.

For example below is a segment of the Hubble Ultra Deep Field taken in Infrared, not visible, light and then masked onto r,g,b as the picture states. This picture is not what you would see as a human looking up at the sky.

i never thought tftv would get this serious about a yellow crosshair

why are people on these forums so smart and well informed

There is also no way to be sure that your brain interprets yellow the same way as anybody else. My yellow could be your green.

Here's a cool video on the subject https://www.youtube.com/watch?v=evQsOFQju08

best thread 2015

i refuse to believe a competitive video game forum is full of nerds like stochast1c

FUCK yellow crosshairs

hey dont say that

Was just gonna post this too lol

lol i overload on cones everyday lol

I am so fucking proud of this thread.

Damn, tf.tv does NOT fuck around when it comes to crosshairs. Well done guys.

god damn these smart individuals

I'd like to think that if he asked for a certain crosshair symbol we would've gotten a lecture on the history of visual design and typography

I mean, there are only so many things you can talk about in threads about crosshair colors before you get rather deep into the topic

but why yellow

I changed my crosshair to yellow because carnage '8)' johnson used it and I wanted to be a big 8)'er just like him

to be fair I have not.

You should use a piece of yellow paper as the crosshair for the real yellow crosshair because your monitor doesn't actually show yellow, it's just a mixture of red, blue and green.
