Removing the colour column of the main index page

[MWP admin]

I was considering to remove the colour column of the main index page of the site [ [url=G:\MarZ-Kreations\WildPlants\WildPlants_Index.html]this page[/url] ] since it is quite useless due the fact there is the thumbnail photo of the flower.

What are your opinions please ?

Should I repalce it with some other data, or leave it names and thumbnail?

I had in mind to replace the colour column with Flowering time or how common it is.
