如何在pygame中更改一段文本的颜色

import pygame
from pygame.locals import *

pygame.init()

width = 800
height = 600
screen = pygame.display.set_mode((width, height))

font = pygame.font.Font(None, 36)  # 使用默认字体和大小

text = font.render("Hello, World!", True, (255, 0, 0))  # 使用红色(RGB: 255, 0, 0)

text_rect = text.get_rect()
text_rect.centerx = screen.get_rect().centerx
text_rect.centery = screen.get_rect().centery

screen.blit(text, text_rect)
pygame.display.flip()

running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False
    
    # 在此处更改文本颜色
    text_color = (0, 0, 255)  # 设置为蓝色 (RGB: 0, 0, 255)
    text = font.render("Hello, World!", True, text_color)
    
    screen.fill((255, 255, 255))  # 填充背景颜色为白色 (RGB: 255, 255, 255)
    screen.blit(text, text_rect)
    pygame.display.flip()

pygame.quit()
