问题描述
我目前正在尝试复制此图像: https://imgur.com/a/IZIPGkg 我正在尝试在背景中制作渐变色,但是我对如何做到这一点一无所知,互联网上基本上没有任何东西。 编辑:如果有帮助,我两端都有RGB颜色。顶部是rgb(154,254),底部是rgb(221,122,80)。
解决方法
粗暴但又合理又快捷有效:
from turtle import Screen,Turtle
COLOR = (0.60156,0.99218) # (154,254)
TARGET = (0.86328,0.47656,0.31250) # (221,122,80)
screen = Screen()
screen.tracer(False)
WIDTH,HEIGHT = screen.window_width(),screen.window_height()
deltas = [(hue - COLOR[index]) / HEIGHT for index,hue in enumerate(TARGET)]
turtle = Turtle()
turtle.color(COLOR)
turtle.penup()
turtle.goto(-WIDTH/2,HEIGHT/2)
turtle.pendown()
direction = 1
for distance,y in enumerate(range(HEIGHT//2,-HEIGHT//2,-1)):
turtle.forward(WIDTH * direction)
turtle.color([COLOR[i] + delta * distance for i,delta in enumerate(deltas)])
turtle.sety(y)
direction *= -1
screen.tracer(True)
screen.exitonclick()
