"Draw Frame":

This button draws a splat frame to the current settings without clearing any previous splats each time this button is clicked.  It's operated either after clearing all splats, or in a "click-reset-click-reset" sequence.  It only  draws the splat frames, in random  RGB colors, unless  the “Auto Fill” box is checked.

If you click it and do not like the frame color, continue clicking it until a more desirable color is drawn.  A future version will have color controls.

Usually, one would set the number of points desired (twice the "star points), then adjust the radii and draw until the desired appearance is achieved.  Then clear splats and draw a final one.  This point set can be copied to the Clipboard for import into a drawing or rendering program

Some drawing also occurs if you have Splat Statistics set in the Preferences dialog, have a visible Stats window, and click in it, but only the frames in random RGB color are drawn.

As long as you don't click the Clear button, each successive splat drawn is "recorded" so that it will be "replayed" in ONE random RGB color when the Stats box is clicked or Grow Box is clicked.

If you want to save a splat in the colors you see it in, use a screen capture utility.
