This week's theme in the MakroTex Challenge is "complementary colours".
"Modern colour theory uses either the subtractive colour model, or the additive colour model, and in these, the complementary/opposite pairs are red & cyan, green & magenta, and blue & yellow." (Wikipedia)
As you can see, I however follow the traditional model - where the primary colors are considered to be red, yellow, and blue, and the primary–secondary complementary pairs are red–green, orange–blue, and yellow–violet. Of these pairs my favourite one is yellow&violet. These sweet flowers still brave the approaching autumn.
This post has also the prosaic part, subtitled "Red tape". To help myself deal with bureaucracy, I have loads of colourful folders (with elastic bands) and ring binders to store the documents. They are many... and the more boring the subject is, the happier colour is chosen.
(The green colour didn't come out well in the photos. It should be lawn green, not some kind of mint.)
Oh, and then I just had to add these recent red-and-green photos...
... and this, one of my favourites, the autumn colours of rosebay willowherbs (Chamerion/Epilobium angustifolium) make a lovely background to the African daisies.
