Color name or number not recognized

Hi,
I have had used Ubuntu 22 and neovim on terminal.
After I upgraded to Ubuntu 24 [GNOME Terminal Version 3.52.0 for GNOME 46], I always get several error messages when I load markdown files, that seem to stem from the same problem, as follows

Error detected while processing BufReadPost Autocommands for "*.txt"..FileType Autocommands for "*"..Syntax Autocommands for "*"..function <SNR>8_SynSet[25]..script .../.local/share/nvim/site/plugged/vim-pandoc-syntax/syntax/pandoc.vim[740]..function <SNR>63_SetupPandocHighlights:
line  111:
E421: Color name or number not recognized: ctermfg=#ffa0a0
line  112:
E421: Color name or number not recognized: ctermfg=#ffa0a0

... and so on
When I use set termguicolors on vim.init, I solve the error messages problem, but I lose the solarized syntax highlight, and the quality of the syntax hightlight itself is seemingly worse.

I use the same configurations on machines with Ubuntu 22, and everything works fine. However, since the problem comes from vim-syntax-pandoc scripts I ask here if you know how to solve it...

Same bug reported here. Sorry.
