Using arraybuffer changes colors of image

I was trying to use a image background for a clock. In order to prevent flickering, I wanted to use a buffer. However, when I draw the image background on the buffer, the image's colors are shifted.
With a buffer (brown colors):

let buf = Graphics.createArrayBuffer(120, 120, 4);
buf.drawImage(
 require("heatshrink").decompress(atob("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")),
  0,
  0,
  { scale: 2 }
);
g.drawImage(
  buf,
  0,
  0,
  {scale: 2}
);

Drawing directly to the screen (intended colors):

g.drawImage(
 require("heatshrink").decompress(atob("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")),
  0,
  0,
  { scale: 4 }
);

Is there any way to make the colors be the intended ones?
