我在Windows上使用CodeBlocks编写代码。但是当我在Linux上使用GCC编译器运行代码时遇到了问题。在Linux上使用system("title heartshape")和system("color XX")函数时，它连续显示以下错误：
“sh：color：找不到命令”
代码中的第12行到第43行是可以绘制心形的代码，在这个问题中没有用到，后面的for(;;)循环可以随着时间的推移连续改变心形的颜色。
源代码如下：

# include <math.h>

# include <stdlib.h>

# define I 20

# define R 340

int main(void)
{
    int i, j, e;
    int a;
    long time;
    system("title Heartshape");
/*codes that use to draw a heart, unhelpful to my question*/
    for (i = 1, a = I; i < I / 2; i++, a--)
    {
        for (j = (int)(I - sqrt(I * I - (a - i) * (a - i))); j > 0; j--)
            printf(" ");
        for (e = 1; e <= 2 * sqrt(I * I - (a - i) * (a - i)); e++)
            printf("\3");
        for (j = (int)(2 * (I - sqrt(I * I - (a - i) * (a - i)))); j > 0; j--)
            printf(" ");
        for (e = 1; e <= 2 * sqrt(I * I - (a - i) * (a - i)); e++)
            printf("\3");
        printf("\n");
    }
    for (i = 1; i < 80; i++)
    {
        printf("\3");
    }
    printf("\n");
    for (i = 1; i <= R / 2; i++)
    {
        if (i % 2 || i % 3)
            continue;
        for (j = (int)(R - sqrt(R * R - i * i)); j > 0; j--)
            printf(" ");
        for (e = 1; e <= 2 * (sqrt(R * R - i * i) - (R - 2 * I)); e++)
            printf("\3");
        printf("\n");
    }
/*codes that use to change the color of the heart*/
    for (;;)
    {
        system("color a");
        for (time = 0; time < 99999999; time++);

        system("color b");
        for (time = 0; time < 99999999; time++);

        system("color c");
        for (time = 0; time < 99999999; time++);

        system("color d");
        for (time = 0; time < 99999999; time++);

        system("color e");
        for (time = 0; time < 99999999; time++);

        system("color f");
        for (time = 0; time < 99999999; time++);

        system("color 0");
        for (time = 0; time < 99999999; time++);

        system("color 1");
        for (time = 0; time < 99999999; time++);

        system("color 2");
        for (time = 0; time < 99999999; time++);

        system("color 3");
        for (time = 0; time < 99999999; time++);

        system("color 4");
        for (time = 0; time < 99999999; time++);

        system("color 5");
        for (time = 0; time < 99999999; time++);

        system("color 6");
        for (time = 0; time < 99999999; time++);

        system("color 7");
        for (time = 0; time < 99999999; time++);

        system("color 8");
        for (time = 0; time < 99999999; time++);

        system("color 9");
        for (time = 0; time < 99999999; time++);
    }
    return 0;
}

这是我项目的全部源代码。
该代码可以在Windows编译器上完美运行，但在Linux上一直显示错误sh: color: command not found。
在我仅仅一周的Linux有限经验中，我只能假设在c中使用system()时，Windows和Linux之间存在差异，并且转义符\3在Linux上也不会显示。
我已经找到了relevant question here，但是这个问题似乎还没有解决，至少答案对我没有帮助。其他的答案似乎太复杂了，无法解决这个问题。
我想知道使用system()函数的区别，以及在Linux上是否有连续改变心形形状颜色的好做法？或者有替代方法吗？
