If RGB(170,255,213) gives a pastel green color display then what is the color code I should use if I want a deeper green color tone display? Is there a list of the color display codes for C++? or where I can lookup for sample color displays? ;)

A short, practical summary: is correct that RGB triples are a standard way to describe colors, and is also correct that the C++ language itself has no concept of color — you get colors through the library or API you use (Win32/GDI, MFC, Qt, SDL, SFML, .NET, browser/CSS, or terminal/console APIs). For GUI work you usually pass 24‑bit RGB (0–255 each). For console apps you either use platform color attributes (Windows console) or ANSI escape sequences (modern terminals).

If you want a "deeper" green compared with the pastel example you posted, there are two common approaches: darken (scale all channels down) or increase saturation (reduce red and blue relative to green). Useful ready-made darker greens: DarkGreen = RGB(0,100,0) (#006400), ForestGreen = RGB(34,139,34) (#228B22), SeaGreen = RGB(46,139,87) (#2E8B57). A simple programmatic method is to multiply each component by a factor < 1 to darken.

Example C++ snippets — darken a color, then how to apply it in Win32 or with ANSI truecolor:

struct RGB { int r,g,b; };
RGB darken(RGB c, double f) { return { int(c.r*f+0.5), int(c.g*f+0.5), int(c.b*f+0.5) }; }

/* Win32: */
COLORREF col = RGB(0,128,0); // deeper green
SetTextColor(hdc, col);

/* ANSI truecolor (terminal): */
printf("\x1b[38;2;%d;%d;%dmHello\x1b[0m\n", r, g, b);

Troubleshooting notes for , , and : if colors look off, check display color depth (16‑bit vs 24/32‑bit), whether the API expects BGR vs RGB ordering, and whether the environment uses sRGB/gamma. For Windows GUI use the RGB() macro or framework color constructors; for older console apps consider the limited 16 color palette and SetConsoleTextAttribute.

Greetings.
Umm, I believe the RGB coding is standard.
What I mean here is that if RGB(170,255,213) = green when displayed in C++, it should be the same when displayed in any other places.
I've found something relevant for you though.

C++ knows nothing of colours. C++ knows nothing of your screen. To alter colours on the screen, you will have to go looking for information on the C++ libraries provided with your operating system, which are available to you through the API.
