The border is:
A morse code, blues mean bars and yellows mean dots.
The message will be "ONE SQUARE OF 6X6 TWO VERTICAL LINES".
Based on it:
We need to tile the $9$ tetrominoes into squares with two vertical lines.
The configuration will be this.
Now:
If we treat black cells as 1's and white cells as 0's, we can read the message in binary.
The message is this.
Maybe there's a slight error here, but you can read the final answer as:
MORSING BINARZ[Y] TETROMINOES

$\begingroup$ So fast! You are of course completely correct. And yes, I made a mistake with the "Y", rendering it as "Z". Sorry about that. Very well done! $\endgroup$ – Jens Nov 8 at 4:23
