How to change RGB values from colormode(255) to colormode(1)?

import turtle

turtle.colormode(255)

turtle.color(130, 50, 50)

If I set the color mode to 1: turtle.colormode(1), what are the RGB values should I put here? turtle.color(?, ?, ?)

Thanks.

Your colormode is set to 1.0, so either the individual color coordinates need to be floats in the range 0.0 to 1.0. Use float / division operator.

Therefore, divide the r, g, b values by 255.

r = 130/255
g = 50/255
b = 50/255
color = (r, g, b)
turtle.color(color)

The docs say:

Return the colormode or set it to 1.0 or 255. Subsequently r, g, b values of color triples have to be in the range 0..cmode.

So, if cmode is 1, you'll need decimal RGB values (130 / 255, 50 / 255, 50 / 255 below):

turtle.color(0.51, 0.197, 0.197)

This is particularly useful with the colorsys module, whose arguments are also in that range:

r, g, b = colorsys.hsv_to_rgb(0.2, 1, 1)  # bright orange HSV
turtle.color(r, g, b)

Setting it to 1.0 means the rgb values should be in the range [0, 1.0], which you can get by dividing each component in 255 mode by 255:

import turtle

turtle.colormode(1.0)

turtle.color(130/255, 50/255, 50/255)
