控制台单调的颜色只有黑白两种，看起来多少有点单调。其实，可以利用SetConsoleTextAttribute函数设置控制台的前景色和背景色。
该函数需要头文件 #include <windows.h>
一、颜色可以混合，遵循配色原理
1. #include <windows.h> 2. #include <iostream> 3. using namespace std; 4. 5. 6. int main() 7. { 8. HANDLE hOut; 9. 10. 11. hOut = GetStdHandle(STD_OUTPUT_HANDLE); 12. 13. 14. SetConsoleTextAttribute(hOut, 15. FOREGROUND_RED | 16. FOREGROUND_GREEN); 17. cout << "This text is yellow." << endl; 18. 19. 20. SetConsoleTextAttribute(hOut, 21. FOREGROUND_GREEN | 22. FOREGROUND_BLUE); 23. cout << "This text is cyan." << endl; 24. 25. 26. SetConsoleTextAttribute(hOut, 27. FOREGROUND_BLUE | 28. FOREGROUND_RED); 29. cout << "This text is magenta." << endl; 30. 31. 32. SetConsoleTextAttribute(hOut, 33. FOREGROUND_RED | 34. FOREGROUND_GREEN | 35. FOREGROUND_BLUE); 36. cout << "This text is white." << endl; 37. 38. 39. return 0; 40. }
二、明暗颜色
1. #include <windows.h> 2. #include <iostream> 3. using namespace std; 4. 5. int main() 6. { 7. HANDLE hOut; 8. 9. hOut = GetStdHandle(STD_OUTPUT_HANDLE); 10. 11. SetConsoleTextAttribute(hOut, 12. FOREGROUND_RED); 13. cout << "Red " << flush; 14. SetConsoleTextAttribute(hOut, 15. FOREGROUND_RED | 16. FOREGROUND_INTENSITY); 17. cout << "Red" << endl; 18. 19. SetConsoleTextAttribute(hOut, 20. FOREGROUND_GREEN); 21. cout << "Green " << flush; 22. SetConsoleTextAttribute(hOut, 23. FOREGROUND_GREEN | 24. FOREGROUND_INTENSITY); 25. cout << "Green" << endl; 26. 27. SetConsoleTextAttribute(hOut, 28. FOREGROUND_BLUE); 29. cout << "Blue " << flush; 30. SetConsoleTextAttribute(hOut, 31. FOREGROUND_BLUE | 32. FOREGROUND_INTENSITY); 33. cout << "Blue" << endl; 34. 35. SetConsoleTextAttribute(hOut, 36. FOREGROUND_RED | 37. FOREGROUND_GREEN); 38. cout << "Yellow " << flush; 39. SetConsoleTextAttribute(hOut, 40. FOREGROUND_RED | 41. FOREGROUND_GREEN | 42. FOREGROUND_INTENSITY); 43. cout << "Yellow" << endl; 44. 45. SetConsoleTextAttribute(hOut, 46. FOREGROUND_GREEN | 47. FOREGROUND_BLUE); 48. cout << "Cyan " << flush; 49. SetConsoleTextAttribute(hOut, 50. FOREGROUND_GREEN | 51. FOREGROUND_BLUE | 52. FOREGROUND_INTENSITY); 53. cout << "Cyan" << endl; 54. 55. SetConsoleTextAttribute(hOut, 56. FOREGROUND_BLUE | 57. FOREGROUND_RED); 58. cout << "Magenta " << flush; 59. SetConsoleTextAttribute(hOut, 60. FOREGROUND_BLUE | 61. FOREGROUND_RED | 62. FOREGROUND_INTENSITY); 63. cout << "Magenta" << endl; 64. 65. SetConsoleTextAttribute(hOut, 66. FOREGROUND_RED | 67. FOREGROUND_GREEN | 68. FOREGROUND_BLUE); 69. cout << "White " << flush; 70. SetConsoleTextAttribute(hOut, 71. FOREGROUND_RED | 72. FOREGROUND_GREEN | 73. FOREGROUND_BLUE | 74. FOREGROUND_INTENSITY); 75. cout << "White" << endl; 76. 77. return 0; 78. }
三、背景颜色
1. #include <windows.h> 2. #include <iostream> 3. using namespace std; 4. 5. int main() 6. { 7. HANDLE hOut; 8. 9. hOut = GetStdHandle(STD_OUTPUT_HANDLE); 10. 11. SetConsoleTextAttribute(hOut, 12. BACKGROUND_RED); 13. cout << "Red " << flush; 14. SetConsoleTextAttribute(hOut, 15. BACKGROUND_RED | 16. BACKGROUND_INTENSITY); 17. cout << "Red " << endl; 18. 19. SetConsoleTextAttribute(hOut, 20. BACKGROUND_GREEN); 21. cout << "Green " << flush; 22. SetConsoleTextAttribute(hOut, 23. BACKGROUND_GREEN | 24. BACKGROUND_INTENSITY); 25. cout << "Green " << endl; 26. 27. SetConsoleTextAttribute(hOut, 28. BACKGROUND_BLUE); 29. cout << "Blue " << flush; 30. SetConsoleTextAttribute(hOut, 31. BACKGROUND_BLUE | 32. BACKGROUND_INTENSITY); 33. cout << "Blue " << endl; 34. 35. SetConsoleTextAttribute(hOut, 36. BACKGROUND_RED | 37. BACKGROUND_GREEN); 38. cout << "Yellow " << flush; 39. SetConsoleTextAttribute(hOut, 40. BACKGROUND_RED | 41. BACKGROUND_GREEN | 42. BACKGROUND_INTENSITY); 43. cout << "Yellow " << endl; 44. 45. SetConsoleTextAttribute(hOut, 46. BACKGROUND_GREEN | 47. BACKGROUND_BLUE); 48. cout << "Cyan " << flush; 49. SetConsoleTextAttribute(hOut, 50. BACKGROUND_GREEN | 51. BACKGROUND_BLUE | 52. BACKGROUND_INTENSITY); 53. cout << "Cyan " << endl; 54. 55. SetConsoleTextAttribute(hOut, 56. BACKGROUND_BLUE | 57. BACKGROUND_RED); 58. cout << "Magenta " << flush; 59. SetConsoleTextAttribute(hOut, 60. BACKGROUND_BLUE | 61. BACKGROUND_RED | 62. BACKGROUND_INTENSITY); 63. cout << "Magenta " << endl; 64. 65. SetConsoleTextAttribute(hOut, 66. BACKGROUND_RED | 67. BACKGROUND_GREEN | 68. BACKGROUND_BLUE); 69. cout << "White " << flush; 70. SetConsoleTextAttribute(hOut, 71. BACKGROUND_RED | 72. BACKGROUND_GREEN | 73. BACKGROUND_BLUE | 74. BACKGROUND_INTENSITY); 75. cout << "White " << endl; 76. 77. return 0; 78. }
四、简化颜色函数
#include <windows.h> void color(int b) { HANDLE hConsole=GetStdHandle(STD_OUTPUT_HANDLE); SetConsoleTextAttribute(hConsole,b); }
具体配色，参见下图：
|
值 |
含义 |
|
STD_INPUT_HANDLE |
标准输入的句柄 |
|
STD_OUTPUT_HANDLE |
标准输出的句柄 |
|
STD_ERROR_HANDLE |
标准错误的句柄 |
wAttributes是用来设置颜色的参数：
|
wAttributes |
颜色 |
对应的值（b） |
|
FOREGROUND_BLUE |
字体颜色：蓝 |
1 |
|
FOREGROUND_GREEN |
字体颜色：绿 |
2 |
|
FOREGROUND_RED |
字体颜色：红 |
4 |
|
FOREGROUND_INTENSITY |
前景色高亮显示 |
8 |
|
BACKGROUND_BLUE |
背景颜色：蓝 |
16 |
|
BACKGROUND_GREEN |
背景颜色：绿 |
32 |
|
BACKGROUND_RED |
背景颜色：红 |
64 |
|
BACKGROUND_INTENSITY |
背景色高亮显示 |
128 |
也就是说SetConsoleTextAttribute函数是靠一个字节的低四来控制前景色，高四位来控制背景色。
例如：
color(4):字体为红；color(8+4):字体为亮红；
color(6):字体为黄；color(8+6):字体为亮黄；
背景色同理。
