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.</p> <div class="admonition seealso"> <p class="admonition-title">See also</p> <p>More information about color spaces can be found at <a class="reference external" href="https://poynton.ca/ColorFAQ.html">https://poynton.ca/ColorFAQ.html</a> and <a class="reference external" href="https://www.cambridgeincolour.com/tutorials/color-spaces.htm">https://www.cambridgeincolour.com/tutorials/color-spaces.htm</a>.</p> </div> <p>The <a class="reference internal" href="#module-colorsys" title="colorsys: Conversion functions between RGB and other color systems."><code>colorsys</code></a> module defines the following functions:</p> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.rgb_to_yiq"> +<code>colorsys.rgb_to_yiq(r, g, b)</code> </dt> <dd> +<p>Convert the color from RGB coordinates to YIQ coordinates.</p> </dd> +</dl> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.yiq_to_rgb"> +<code>colorsys.yiq_to_rgb(y, i, q)</code> </dt> <dd> +<p>Convert the color from YIQ coordinates to RGB coordinates.</p> </dd> +</dl> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.rgb_to_hls"> +<code>colorsys.rgb_to_hls(r, g, b)</code> </dt> <dd> +<p>Convert the color from RGB coordinates to HLS coordinates.</p> </dd> +</dl> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.hls_to_rgb"> +<code>colorsys.hls_to_rgb(h, l, s)</code> </dt> <dd> +<p>Convert the color from HLS coordinates to RGB coordinates.</p> </dd> +</dl> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.rgb_to_hsv"> +<code>colorsys.rgb_to_hsv(r, g, b)</code> </dt> <dd> +<p>Convert the color from RGB coordinates to HSV coordinates.</p> </dd> +</dl> <dl class="py function"> <dt class="sig sig-object py" id="colorsys.hsv_to_rgb"> +<code>colorsys.hsv_to_rgb(h, s, v)</code> </dt> <dd> +<p>Convert the color from HSV coordinates to RGB coordinates.</p> </dd> +</dl> <p>Example:</p> <pre data-language="python">>>> 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) +</pre> <div class="_attribution"> + <p class="_attribution-p"> + © 2001–2023 Python Software Foundation<br>Licensed under the PSF License.<br> + <a href="https://docs.python.org/3.12/library/colorsys.html" class="_attribution-link">https://docs.python.org/3.12/library/colorsys.html</a> + </p> +</div> |
