body: <p>I got small problem with scss-lint, I am trying to run in a simple file and after changes in the scss-lint.yml , still not loading my config.</p>
  
  <p>scss file: _headlines.scss</p>
  
  <pre><code>// Headlines

    @include rem-size(60px);
    color: palette(grey, light); 
    font-weight: $font-weight--book;
    line-height: $line-height-base;
    margin-top: 0;
  }
  </code></pre>
  
  <p>scss-lint.yml</p>
  
  <pre><code># Default application configuration that all configurations inherit from.
  
  scss_files: "scss/**/*.scss"
  plugin_directories: ['.scss-linters']
  
  # List of gem names to load custom linters from (make sure they are already
  # installed)
  plugin_gems: []
  
  # Default severity of all linters.
  severity: warning
  
  linters:
    ColorKeyword:
      enabled: false
  
    ColorVariable:
      enabled: false

  <pre><code>scss/_headlines.scss:5:1 [W] TrailingWhitespace: Line contains trailing whitespace
  scss/_headlines.scss:5:18 [W] ColorKeyword: Color `grey` should be written in hexadecimal form as `#808080`
  scss/_headlines.scss:5:18 [W] ColorVariable: Color literals like `grey` should only be used in variable declarations; they should be referred to via variable everywhere else.
  scss/_headlines.scss:9:1 [W] FinalNewline: Files should end with a trailing newline
  </code></pre>
  
  <p>ColorKeyword is defined as false in my scss-lint.yml but still runing someone know what is happen? </p>
