Learning my way around WebGL but can't figure out how to change a simply background from black to white in this. It appears that this
gl.clearColor(255.0, 255.0, 255.0, 1.0);
does indeed change the background color to white, BUT as soon as the animation loads it updates the background back to black.
I'm stumped here. How do you change the background color to white and keep it from changing back to black?
The simplest way i can share what i'm doing is this example on codepen. if you can tell me how (and hopefully why) to change the background color on this codepen then you would help me significantly.

Does anyone know what the colors on the main verticals represent? Some are obvious, like blue is html, purple is css.. but I'm unsure what's the difference between pink vs. light green.

The Fine Manual explains that the colors are arbitrary:
DevTools assigns scripts random colors. In Figure 16, function calls from one script are colored light green. Calls from another script are colored beige. The darker yellow represents scripting activity, and the purple event represents rendering activity. These darker yellow and purple events are consistent across all recordings.
View network requests uses a fixed set of colors:
Requests are color-coded as follows:
HTML: Blue,
CSS: Purple,
JS: Yellow,
Images: Green
I was reading an article and they work on the gray image from green channel. They work with retina images and detect blood vessels on it.
My questions are that:
What does 'gray image from green channel' mean?
How can I get this gray image from green channel?
What is the difference between the gray image which is result of this matlab code I = rgb2gray(RGB) and gray image from green channel?
Thank you.
Just for fun, you can do it with ImageMagick which is installed on most Linux/Unix boxes and available for free for Windows and OSX like this:
Starting with this image:
convert plant.jpg -separate -delete 0,2 out.jpg
That separates the image into Red, Green and Blue channels, then deletes the Red and Blue channels leaving just the Green channel which then becomes a monochromatic (grey) representation of the amount of green in each pixel - so the green of the plant shows up the brightest/lightest.
Following on from this question.
When I draw the letters I'm getting a dark border around some areas. Below is an example zoomed 4x. The letter on the left is drawn with OpenGL. The letter on the right is my bitmap font atlas in Photoshop colour adjusted to match what is being drawn by my game. As you can see, the 's' on the left has noticeable dark borders in some areas.
I've played with various blending options but can't work out what's causing it. If someone could tell me what the cause is and how to fix it that's be appreciated.
In the background of my view, I draw a light blue color. And in the middle, i have a square box that is supposed to have an even lighter gray in it that has a 20% transparency. But for some reason the transparency is on top of a black background instead of a blue. I'm sorry If i'm not being clear.
You're probably using the wrong compositing mode to draw the smaller box. Show us your code.
