Context
Bug, "Spelling of 'turquise' in Impress Table Design" indicates that the  color was spelled   in Impress module of LibreOffice (and certainly in Apache OpenOffice). A straightforward fix has been applied to the module but the documents made before this fix and which use tables with  styles are concerned.

Symptoms
A duplicate  style will be present for old files not fixed.

How to fix
Just follow these steps:
 * Open the file
 * Select the table

Notice the duplicate turquoise style in the Table Design pane (at bottom right)


 * Click the first turquoise style at top right of this same pane
 * Save the file

That's it!
