我如何让两条线在一个循环中绘制成相同的颜色？

import matplotlib.pyplot as plt
import random

# 设置循环次数和线条数量
num_iterations = 10
num_lines = 2

# 循环绘制线条
for i in range(num_iterations):
    # 生成随机的RGB颜色值
    r = random.randint(0, 255)
    g = random.randint(0, 255)
    b = random.randint(0, 255)
    color = (r/255, g/255, b/255)  # 将RGB值转换为0-1范围的浮点数

    # 创建一个新的绘图窗口
    plt.figure()

    # 绘制每条线条
    for j in range(num_lines):
        # 设置线条颜色
        plt.plot([0, 1], [j, j], color=color)

    # 显示绘图窗口
    plt.show()
