I want to try to dye a string that is defined by a cin >> input, and make the string reference the color each time the string is called.
I.E.
string firstName
cin >> firstName
how do I do this?

You are using a lot of std::string types and always copy them. Consider using const char* pointer since you are only using raw literal strings. This will avoid unnecessary copys and allocations (this of course depends on the implementation of std::string and if its using short string optimisation)

And I took a deeper look at your code. Why are you not just using an enum value that already has the value needed for the win32 api? Something like

enum class hue {black = 0, .... }

Then you would just need to overload the stream operator for the enum.

See errors in file.

Not all functions are marked with the keywords inline or constexpr or are templated. As a result if one would include this headder more than twice the linker is going to complain.

I'd like to use this lib with wcout to dispaly utf16 characters, but when writing
wcout << dye::green(L"hello");
I get the error:

error: no match for 'operator<<' (operand types are 'std::wostream' {aka 'std::basic_ostream<wchar_t>'} and 'dye::R<const wchar_t*>' {aka 'dye::colorful<const wchar_t*>'})
     wcout << dye::green(L"hello");
     ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any quick solution for this issue?

_there are still as many as 300 more link errors like this happend when i tried to compile the program.
_when you include color-console library inside a user defined class this link errors happen, but if you use it without being included
in any class no errors generate.

please help me what shoul i do now?

FIX the problem sooooooooooooooooooon

thank you very much helped me a lot!
I'm making a code editor based on the vim type terminal

Not sure what library conflicts with windows.h as some library also defines byte, was necessary to add #define WIN32_LEAN_AND_MEAN at the top of the header file to make it work, without the macro, throws a bunch of compilation errors like this:
In file included from c:\mingdef\mingw\x86_64-w64-mingw32\include\wtypes.h:8, from c:\mingdef\mingw\x86_64-w64-mingw32\include\winscard.h:10, from c:\mingdef\mingw\x86_64-w64-mingw32\include\windows.h:97, from {path} headers/color.hpp:11, from {path} testing.cpp:7: c:\mingdef\mingw\x86_64-w64-mingw32\include\rpcndr.h:64:11: error: reference to 'byte' is ambiguous 64 | typedef byte cs_byte; | ^~~~

Add a new macro that can support function-like call for hue namespace

#define color(operation,content) operation << content << hue::reset

std::cout<<color(hue::red, "Hello world!"); //(color red)
std::cout<<color(hue::red, "Hello world!") << "just kidding"; //first one color red
std::cout<<color(hue::red, "Hello world!" << "just kidding") ; //2 string color red

all three work, everything outside of the color macro will be reset to original, because this macro call hue::reset after all operation
