I could not get a chrome ore. Singas looks purple and not yellow.

I fixed them.
Need to add text in a file

%AppData%\Roaming\Factorio\mods\PyCoalTBaA_0.9.8\PyCoalTBaA_0.9.8\prototypes\angels-mods\overrides\overrides.lua

if data.raw.resource['ore-chromium'] ~= nil then
if data.raw.fluid['gas-synthesis'] ~= nil then
data.raw.resource['ore-chromium'].minable.required_fluid = 'gas-synthesis'
end
end

if data.raw.resource['ore-zinc'] ~= nil then
if data.raw.fluid['gas-synthesis'] ~= nil then
data.raw.resource['ore-zinc'].minable.required_fluid = 'gas-synthesis'
end
end

if data.raw.resource['ore-nickel'] ~= nil then
if data.raw.fluid['gas-synthesis'] ~= nil then
data.raw.resource['ore-nickel'].minable.required_fluid = 'gas-synthesis'
end
end

Thank you for your contribution!
