#include<GL/glut.h>

void disply()
{
    glClearColor(191/255.0, 239/255.0, 255/255.0, 1);
    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);
          glColor3ub(255, 130, 171);
          glVertex3f(1.0, 0.0, 0.0);

          glVertex3f(0.0, 0.0, 1.0);
          glVertex3f(1.0, 1.0, 1.0);
    
    glEnd();

    glutSwapBuffers();
}

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("01370984_WEEK3");
    glutDisplayFunc(disply);

    glutMainLoop();
}

For this picture, you can search color's RGB values by using mspaint. 



Also can check coordinate using mspaint.
