How Can I Make the HTML Tag Colours Brighter or Stronger ?

Hi - suppose I have a section of HTML code where there is a bunch of nested div's. Storm very nicely colours all the divs - but the colours are so pastle that they are hard to see - how can I make them stronger / brighter ? I have looked inside settings / editor / colour and fonts / html   but that does not do it.

Any ideas ?

Many thanks !
