I tried that and what I got was this:
testout1.bmp
testout2.bmp
maybe I did something wrong?
how exactly did you do it? - how did you map the colors?

Thank you for explanation.
How I got image and rendered to final?
Image is taken from MiST FPGA with SoC ZX Spectrum with ULA graphic chip, then converted by renderer made for Commodore 128 VDC chip - rendering at moment when find not exact color, runs dithering, it has no command line options. I got source from author, it's written in C. Sadly for now I know programming of PCs only Visual Basic, began C++... so any time will go to moment when I will re-programming source.
Sadly in PC world is assembler full of routines which can be written in other PL, I know assembler of 8-bit and 16-bit computers, but in this era is assembler something what no everybody knows its low level...
But thank you for clearing me it and I will search for free tool which it can do at least like Corel or ? better ?.

I used DPScan for the palette swapping and as there are both RISC OS and Windows versions of the software, I could experiment with using palette file inside application folder of ZX Spectrum emulator on RISC OS. With that palette file inserted inside DPScan palette directory, it converted images with perfect ZX Spectrum colours and after that it was just manual work for replacing colours inside that palette with new values from this thread and saving palette with different name to same directory.
I tried earlier to make my own palette from scratch and it gave wrong colours in wrong places, but taking colour order from that existing palette just works and only need select palette and press button for correct looking replacement colours for the image.
sounds interesting if you have access to both RISC OS and windows [which I don't] - but can you guarantee than it will replace the right colors in the right place for other images just by pressing button, or will there still be the manual work to do in each case? - can you try it with the 'Fist' image?

Here is the "fist" image after press button palette swap.

I am pretty sure it works perfectly for ZX Spectrum images because the palettes are so similar and at least on my tests the resulting images look good.
thanks - so can you do this if you do not have access to risc - if so can you post up the palette, because I would love to give that a test

Actually the palette imported from your images works fine with the software I used, and the colours from the ZX Spectrum palette get swapped to equal colours from another palette.
DPScan is freely downloadable graphics utility on RISC OS, but on Windows it only comes free with Windows version of Ovation Pro DTP software. Palette files it exports/imports are RISC OS palette files and as such may not be much use for Windows users without DPScan. Anyway your palette works already as intended and it seems DPScan is just pretty good at substituting colours to closest colour on another palette.
Nice!
Boys you're great!
I try to do it by DPScan, if it will be successful I'll report.

Sadly download not found

DPScan download link listed here: http://www.davidpilling.info/cd/software.html
manual here: http://www.davidpilling.info/cd/Davi...can/DPScan.pdf - also listed on previous link
seems to work ok on my win 10 x64 - do need to be in admin mode to install it, ie run installer as admin
quite a useful utility
it may only work under trial mode though if you have not bought ovation pro - ie it may stop working after a while - seems to be no clear info on this that I could find...
edit - at the bottom of the above linked page:so make of that what you will.....Note DPScan cannot be used unless Ovation Pro is registered
