I've measured the cable and checked the description on both sides:

DIN		SCART
1 YS/CMT GND	4,5,9,13,17	GND
2 Audio		2,6		Audio
3 GND		8		Switch +12V
4 AV/CMT IN/OUT	20		Composit video in
5 CSYNC		16		RGB blanking
6 G		15		RGB red input
7 R		11		RGB green input
8 B		7		RGB blue input

Look at where pin 6 and 7 of the DIN go.
MSX startup screen, Black (0,0,0), White (7,7,7) and Blue (0,0,7). Black and white don't care how the RGB is connected, but blue does and that one is correct according to the diagram. So I did a test with color=(15,7,0,0) which made color 15 red (ok), color=(15,0,7,0) which made color 15 green (ok) and color=(15,0,0,7) which made color 15 blue.
All as they should be, but looking at the diagram not as expected.
Will hook up a Sony now and make the same "screen shot"

Edit: Now the guy who sold me this WSX told me he likes hardware. I do not know the guy, never heard of him before and don't remember his name now. Could it be he altered his RGB output connector? That'd be weird, since it's easier and saver to patch a cable.

Here's a Panasonic FS-A1WX

and a Sony HB-F1XV

with the exact same cable as used on the Panasonic FS-A1WSX

Now breaks me the woodenshoe.

Not really (editing this again cuz the whole url thing went bananas).
Find "Normal" and WSX here and compare the RED and GREEN pins. The WSX gets them from other pins: Pins 6 and 7 are swapped.

And the second one seems to have more exact color like i have on my Trinitron.
@Grauw - why they should have swapped two color signals for the Turbo computers? This is more than weird btw...

You are looking at the din connector from the wrong side, ie. the number should be flipped,
(1<>3, 4<>5, 6<>7) while those in the center obviously are correct.

I never made that cable. I checked the wiki: https://www.msx.org/wiki/RGB_(8-pin_DIN_45326)
If the wiki is wrong, I invite you to correct it :)

* please copy/paste the url as this CMS cuts the url right after the underscore.

I'm not saying that the wiki is wrong, I'm just pointing out that *maybe* you looked at the numbers from the wrong side of the connector so you could have misnumbered your cable-connector correspondence.
And it's not 6 and 7 that are swapped in your table, I would be VERY suspicious of the GND and +5v that are swapped (CVBS and Blanking too).

And while we are at it:

Is this how CVBS can look on a CRT screen?

There's NO WAY that that screenshot is from a CVBS signal. You wouldn't be able to see 80 columns so clearly, there would be color fringing/dithering everywhere.

I agree, that WSX is definitely outputting RGB in that image.

Here are 2 images from an ST on CRT, you'll spot which one is CVBS and which is RGB:

That would suggest that the pinout in the wiki is wrong?
