Download blocks as image has different colors for input fields over 1 year ago

AI Summary: The task is to debug and fix a bug in the MIT App Inventor Blocks Editor where the color of input fields in downloaded block PNG images is incorrect. The input fields appear as black instead of their correct orange color. The solution requires investigating the image generation process within the Blocks Editor, identifying the source of the color discrepancy, and correcting it to ensure the downloaded PNG accurately reflects the colors in the editor.

Complexity: 4/5
