After writing a small image converter for pomppo's 1-bit sprites I hacked together a color image "importer".

It reads a 128x128, 16 color image, and spits out something you can paste in a p8 file, in the gfx section.
The cartridge here just displays it.

I don't know if there is any point in doing this... a "fullscreen" 128x128 image takes up Pico-8's all gfx memory, so after that there are no more room for any sprites...
One use case would be importing a sprite sheet, so an artist can work in his/her favorite editor program, or something.

Anyway here is it.
It is a (really-really-really hacky) Processing program.

Just change the image name, run the sketch, and the data is copied to the clipboard (or if not, you can copy it from the console window).

Paste it over the gfx data in the p8 cartrigde file, and the sprites will be replaced by your picture.

void setup() {

dimg.copy(img, 0, 0, img.width, img.height, 0, 0, img.width, img.height);

void draw() {
image(dimg, 0, 0);
}

void mousePressed() {
String simg = "";
int counter = 0;
dimg.loadPixels();
for (int i = 0; i<dimg.pixels.length; i++) {
Integer s = dimg.pixels[i];
simg += converter.get(s);
//println("Got: "+hex(s)+" -> "+converter.get(s));

counter++;
if (counter==img.width) {
  for (int o = counter; o<128; o++) {
    simg += "0";
  }
  simg += "\n";
  counter = 0;
}

}

StringSelection data = new StringSelection(simg);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(data, data);

println(simg);
}

As I mentioned this is really hacky - the stupidest thing is that looks for exactly same colors, so it is a good idea to use the following palette.
This is a photoshop .act file, load as the color table of your indexed image.
