How do I select elements which have property `color:lightGreen` in CSS using jQuery and then change it to `#666`?

Example Html:

```
<a id="ctl00_ContentPlaceHolder1_GridView1_ctl17___ID_DetailsHyperLink" 
    class="CorporateHyperlink" 
     href="/EstimateSite/Estimate/Details.aspx?ID=234"
     style="color:LightGreen;">Details</a>

```
