How can I configure the format for the value for Sass variables, during the conversion to CSS?
<p>Me and my team are using Sass (through <strong><em>grunt-contrib-sass</em></strong>) to build our stylesheets. However, when we commit to Git, we found certain differences to the CSS that's being generated among our team members. 
When storing a color in a variable, and applying it to a class, we have two different outputs:</p>

<p>Output 1:</p>

<pre><code>outline: #90B2E9 solid 1px;
</code></pre>

<p>Output 2:</p>

<pre><code>outline: #90b2e9 solid 1px;
</code></pre>

<p>Output 1:</p>

<pre><code>background: -webkit-linear-gradient(top, #FFFFFF 0%, #A6C9DB 100%);
</code></pre>

<p>Output 2:</p>

<pre><code>background: -webkit-linear-gradient(top, white 0%, #a6c9db 100%);
</code></pre>

<p>As you an see, one machine generates Hex codes in lower case, other in upper case. One generates Hex code, one the color alias.</p>

<p>Is there a way configure Sass to always format color codes the same way, for all out machines?</p>
