Coordinates in all of these color spaces are floating point values. In the YIQ space, the Y coordinate is between 0 and 1, but the I and Q coordinates can be positive or negative. In all other spaces, the coordinates are all between 0 and 1. 參見 More information about color spaces can be found at <http://poynton.ca/ColorFAQ.html> and <https://www.cambridgeincolour.com/tutorials/color-spaces.htm>. The [`colorsys`](#module-colorsys "colorsys: Conversion functions between RGB and other color systems.") module defines the following functions: `colorsys.``rgb_to_yiq`(*r*, *g*, *b*)Convert the color from RGB coordinates to YIQ coordinates. `colorsys.``yiq_to_rgb`(*y*, *i*, *q*)Convert the color from YIQ coordinates to RGB coordinates. `colorsys.``rgb_to_hls`(*r*, *g*, *b*)Convert the color from RGB coordinates to HLS coordinates. `colorsys.``hls_to_rgb`(*h*, *l*, *s*)Convert the color from HLS coordinates to RGB coordinates. `colorsys.``rgb_to_hsv`(*r*, *g*, *b*)Convert the color from RGB coordinates to HSV coordinates. `colorsys.``hsv_to_rgb`(*h*, *s*, *v*)Convert the color from HSV coordinates to RGB coordinates. 示例: ``` >>> import colorsys >>> colorsys.rgb_to_hsv(0.2, 0.4, 0.4) (0.5, 0.5, 0.4) >>> colorsys.hsv_to_rgb(0.5, 0.5, 0.4) (0.2, 0.4, 0.4) ``` ### 導航 - [索引](../genindex.xhtml "總目錄") - [模塊](../py-modindex.xhtml "Python 模塊索引") | - [下一頁](imghdr.xhtml "imghdr --- 推測圖像類型") | - [上一頁](chunk.xhtml "chunk --- Read IFF chunked data") | -  - [Python](https://www.python.org/) ? - zh\_CN 3.7.3 [文檔](../index.xhtml) ? - [Python 標準庫](index.xhtml) ? - [多媒體服務](mm.xhtml) ? - $('.inline-search').show(0); | ?
