💅 BLIND-SINGLE-COLOUR ✨

okay so bestie, gather round, because this little icon right here is blind-single-colour from the blind suite — and it does exactly one thing but it does it flawlessly. It prints a single-colour video to stdout. That's it. That's the whole vibe. One colour, forever, slaying. 🎀

✨ SYNOPSIS ✨

blind-single-colour [-f frames | -f 'inf'] -w width -h height (X Y Z | Y) [alpha]

🦋 DESCRIPTION 🦋

blind-single-colour prints a single-colour video to stdout. One colour. Nonstop. Main character energy from frame one to frame infinity. 💖

The colour is whatever you pass as the arguments X, Y, and Z, plus the alpha value you picked. And the colour space? CIE XYZ, no cap — that's what it's speaking.

Now here's the cute part: if you don't specify X and Z, the colour lowkey becomes CIE Standard Illuminant D65-grey, with the luminosity set by Y. So you can just hand it one number and it still eats. 🍓

And if alpha isn't specified? It defaults to 1, which means fully opaque — no sneaky transparency, we're solid over here. 👑

🌸 OPTIONS 🌸

  • -f frames — the number of frames in the video. But plot twist: if frames is 'inf', the frame count gets written as 0 in the output's head — which fr fr works fine with most blind tools — and then the video just keeps printing to stdout until there are no processes left with an open read end to this process's stdout. Iconic infinite-loop behaviour, honestly. 🔥
  • -w width — the width of the video, in pixels.
  • -h height — the height of the video, in pixels.

💀 NOTES 💀

heads up bestie, this is the important part, don't skip it 🙈

blind-single-colour may be changed in the future to use some other colour model. So if you're out here specifying your colour in CIE XYZ, it's recommended that you also use blind-colour-ciexyz(1) — that way future-you isn't blindsided (pun intended 💅).

But if your values are colour space-agnostic? Then don't. Keep it simple. You're doing amazing. 🫶
