I've noticed that this color is somehow preferred over pure blue or blue-violet. Vista and Windows 2008 have largely adopted this color. Many dating sites seem to prefer this one over blue or violet.

I enjoy using UNIX/bash commands that support coloured output. Consequently, I have a few aliases defined which automatically enable coloured output of the commands that I know support this option. However, I'm sure there are hundreds of commands out there that support coloured output - I'd like to know what they are. The ones in my ~...

Hi everyone, I've a project at the moment, in Java, which uses a filetype which is inherently in the YCbCr colorspace. Within this, there is a lot of number crunching happening behind the scenes (which I've had to code) to convert to RGB from the YCbCr values. This is done per-pixel, per-frame, at 25 frames per second... The project mu...

What is the best way to turn strings like "red", "green", "yellow", "aliceblue", etc... into the actual System.Drawing.Color value? I was looking at reflection and something about that didn't seem right. ...
I have some Javascript which "animates" a colour change on an HTML element, as follows: var element = document.getElementById("someid"); while (i < 255) { element.style.color = 'rgb(' + i + ',' + i + ',' + i + ')'; i++; slowMeDown(); // This function runs for a few ms to slow the process down } As you can see, this changes...
Maybe I've had too much coffee, maybe I've been working too long, regardless, I'm at a loss as to what this method does, or rather, why and how it does it, could anyone shed some light upon me?

I'm looking for some kind of formula or algorithm to determine the brightness of a color given the RGB values. I know it can't be as simple as adding the RGB values together and having higher sums be brighter, but I'm kind of at a loss as to where to start. ...

I have gotten somewhat close us...

Example: If I draw a black rectangle, the obvious colour f...
If I have two colors defined by their RGB values, can I average the Red, Green and Blue values and then combine to define a third color that looks like a visual average of the two? ie NewColor = (R1+R2)/2,(G1+G2)/2,(B1+B2)/2 EDIT1: Thanks for all the responses. For my current needs, I am only dealing with color pairs that are shades o...
