Interesting. I got it to imagine it was a human drawing a self portrait (via SVG code), and then to add colour (and a few extra bits like a speech bubble where I told it to write what it wanted to say) and it came up with this.
To be fair, when it added the colour, #ChatGPT did also say:
"In this example, I added the fill="#ffc0cb" attribute to the element that represents the head of the self-portrait, giving it a pink color. You can of course use any other color you like by replacing the hexadecimal color code #ffc0cb with a different one. Some common color codes include:
#000000 (black)
#ffffff (white)
#0000ff (blue)
#00ff00 (green)
#ff0000 (red)
#ffff00 (yellow)
You can also use the RGB (red, green, blue) or HSL (hue, saturation, lightness) color models to specify colors in a more intuitive way. For example, the pink color used in the example above can also be written as rgb(255,192,203) or hsl(350,100%,88%)."
But hmmmm, interesting default choice!
It also helpfully provided a link to https://www.w3schools.com/graphics/tryit.asp?filename=trysvg_polygon where the code can be tested
