This room is to discuss the following puzzle:

@2012rcampion I'm checking your color translation right now

Just checking panel 4 at the moment, it seems correct. Your colour-replace table is slightly odd though (going to post an image in a min.)

Top row: "Puzzle original colors" (panel 4), Bottom row: your image colors (panel 4). Can I assume you did the same replacement in all panels?

By "slightly odd" I meant, the replaced colors are also not very disginuishable

I might want to suggest that we use the "replacement table" I've used when creating the puzzle (-not because it is much nicer, but it makes comparison easier...)

Note that the order of colour-pairs is deliberately unsorted to not give any spoilers away.

Forget my table above. I'll redo...

Original (with color-bar):

And recolored:

And for P2: Original (with color-bar):

And recolored:

And for P3: Original (with color-bar):

And recolored plus lines:

@BmyGuest I just multiplied all the colors below a certain threshold by 8. I didn't increase the multiplier to keep a distinction between the turned-on and turned-off lights.

But it looks like you're not distinguishing between them?

@2012rcampion Not certain what you mean by "turned-on" and "torned-off", could you explain? What I did was just a "Oh, those aliense have better eye-sight, let's recolorize to help our weak human eyes to see the differences"-replacement.

Or, in other words: The ACTUAL color is not important, but that there are different colors, that is very important. Make it visually easier to see...

(I was actually also thinking to do a "numbered" black & white verision, but that was too much work for me. Feel free to do it, though ;c) )

Ah, "dark" = turned off ? No, the panels are static. Nothing will "switch" on/off on P1-P4. They could be paintings on a wall too...

And - just in case you've missed it - I use the identical color-enhancement (or color-switch) in all panels.

@BmyGuest I wasn't implying that they'd switch, although it's nice to confirm they don't.

Essentially, the "make some colors very, very dim" was an additional layer of the puzzle, now taken away. One could "repost" the puzzle with the replaced colours and wouldn't change the puzzle. I think you deserved the "50rep" bounty for this part of the puzzle ;c)

This is what I get when I normalize the palette from your pictures, is this correct?

i.e. there appears to be no relationship between the 'before' and 'after' colors (since, as you say, the actual color doesn't matter)

The important part is to keep X distinctive colors, so you don't need to normalize anything. It is just important to not accidently mess colors up. I think my colours are fairly distinctive (in the images above), but as said: a "black&white"-version (with symbols?) would be nice to have too - and wouldn't break the puzzle.

However, there is one property of Panel P2 which should not get "destroyed" in the process. Both the orignal, my replaced and your replaced images have it at the moment.

What I'm trying to get at is, for example, in the original image, some of the dots are very dark red, but in your new image they are bright yellow. I just want to double-check that the colors didn't accidentally get swapped around.

(i.e. they're supposed to be bright red instead)

I did a "search-replace" in Corel, so it should be okay, but it never hurts to double-check. As long as all dots of SAME color in the orignal image are of SAME color in the "nehanced" (and no others are), it's okay.

As mentioned in the "hint" of the puzzle: The idea is, that for an alien all those colors are very different - it's just us poor humans which are all "color blind" to some extend...

...but they're not different in terms of brightness to them

i.e. they wouldn't see a division into 'turned on' and 'turned off' groups

Ah, that's what you mean. No. "Brightness" is just a proxy for "contrast".

I could have done very "slight shades of one colour", but when testing it, it didn't work that nicely as hiding things in "close to black".

(But it's a good point. Hadn't thought that one could interpret it like that... Well, always something to improve on.)

I'm going to leave this discussion now. But if you get any further or want to post some of your ideas/progress, I'll check in later.

Also: I think the question "different brightness" vs "differnt color" is very relative. I've chose rather "extremes", but how many "different colours" are f.e. in the following image:

One (Alien) could say: These are 6 different colours. Others might say: no, just 3 different colors, but blue comes in different brightness...

Trying to put this another way; when I look at the color palette, I'd say "there are two groups of dots, the bright dots and the dark dots." You're saying that I should be saying, "there are 17 groups of dots, one for each color," ignoring the brightness differences.
