Sure. Send me the list of palette RGBs and any mood ratings you have for each sprite, and I’ll plot the data and highlight the colors that correlate with happiness.

Here’s what the data shows, straight out of the numbers: - The highest moods line up with warm, saturated colors: the bunny’s peachish tone (mood 9) and the kangaroo’s gold (mood 8) are the top performers. - Mid‑range moods come from neutral greens: the turtle’s lime green sits at 5, and the owl’s sky blue gives 7, so blue is a bit less positive but still better than the deep indigo of the fox. - The low moods cluster around deep, low‑saturation reds and blues: the fox’s midnight blue (3) and the dragon’s scarlet (2) are the worst. If you plot hue versus mood, you’ll see a positive slope from 0° to about 60° (warm colors), a plateau around 120° (greens), then a sharp decline past 200° (blues and reds). So, keep the palettes in the 0–90° hue range and push the saturation up if you want more smiles. The deeper, colder tones will bring the frowns back up again.
