Help with pattern colors

[Fredrik Hareide]

I'm making two of the Koi patterns on 1x2 tiles and need help selecting colors.

On the first one I have selected Blue, White, Coral. Don't know about the last color.

This one has orange and reddish brown (as the title says) But the rest?
Might as well do these while I'm at it. So we have all the fish

The Kois are already in the library: https://library.ldraw.org/search/part?s=koi

Oh, I didn't find them when I searched. I can see that one of them has a mistake. No color on the part I was asking for. That looks like a greyish color.

Added an image to make it clearer

But I still need help with the colors for the two remaining fish.

For the first one I'd say Blue, Yellow and Bright Light Orange
And the second one, Blue, White and Bright Light Orange

But I really have doubt between Orange and Bright Light Orange depending on the pictures I look at. Rebrickable has different photos:

According to that one it might be that first one is Bright Light Orange and second one Orange unless it's an optical effect that mislead me

I have real-life parts and checked the colours:

   

3069bpb0865 (right): Bright light orange(191), Orange(25), Blue(1)
3069bpb0866 (left): White(15), Orange(25), Light bluish grey(71), Blue(1)

The outer area of orange spots in 3069bpb0866 is not a intentional lighter shade, but a colour bleeding (orange on white).

If needed, I can provide hi-res scan of these patterns.
