title: WebGLRenderingContext.clearColor()
slug: Web/API/WebGLRenderingContext/clearColor
translation_of: Web/API/WebGLRenderingContext/clearColor
---
<div>{{APIRef("WebGL")}}</div>
<p>Метод <strong><code>WebGLRenderingContext.clearColor()</code></strong> из <a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> определяет значения, используемые для задания цвета во время очистки буферов цвета.</p>
<p>This specifies what color values to use when calling the {{domxref("WebGLRenderingContext.clear", "clear()")}} method. Эти значения находятся в пределах от 0 до 1.</p>
<h2 id="Syntax">Syntax</h2>
<pre class="syntaxbox">void <var>gl</var>.clearColor(<var>red, green, blue, alpha</var>);
</pre>
<h3 id="Parameters">Parameters</h3>
<dl>
<dt><code>red</code></dt>
<dd>A {{domxref("GLclampf")}} specifying the red color value used when the color buffers are cleared. Default value: 0.</dd>
<dt><code>green</code></dt>
<dd>A {{domxref("GLclampf")}} specifying the green color value used when the color buffers are cleared. Default value: 0.</dd>
<dt><code>blue</code></dt>
<dd>A {{domxref("GLclampf")}} specifying the blue color value used when the color buffers are cleared. Default value: 0.</dd>
<dt><code>alpha</code></dt>
<dd>A {{domxref("GLclampf")}} specifying the alpha (transparency) value used when the color buffers are cleared. Default value: 0.</dd>
</dl>
<h3 id="Return_value">Return value</h3>
<p>None.</p>
<h2 id="Examples">Examples</h2>
<pre class="brush: js">gl.clearColor(1, 0.5, 0.5, 3);
</pre>
<p>To get the current clear color, query the <code>COLOR_CLEAR_VALUE</code> constant which returns a {{jsxref("Float32Array")}}.</p>
<pre class="brush: js">gl.getParameter(gl.COLOR_CLEAR_VALUE);
// Float32Array[1, 0.5, 0.5, 1]
