Thank you card with colourblocks

I'd like to enter this card into the : CAS Colours & Sketches Challenge # 159 and the Addicted to CAS Challenge # 80: bloom.

Colour blocking is mostly done in fashion and interiors, where two or more contrasting blocks of colour are used next to each other, usually solids and colours you might not put together in an outfit yourself like orange and purple or yellow and hot pink etc. CAn't say I will ever wear these outfits ;-) I like a certain red and purple together but that's as brave as I get lol.

I used the idea of colourblocking for my flowers.
These are dies from Simon Says Stamp (single roses) and to get the colours I just swiped the inkpad onto some scrap cardstock. same for the background (Distress inks spun sugar with some Ranger dye ink gumball combined, picked raspberry and carved pumpkin). When you diecut these roses you're left with outlines and a nice graphic looking swirly bit I will use on another card ;-)....
So I stuck the die cuts on contrasting colours and cut them out. I swiped the inkpad along the edges to neaten them up, what you usually would do with a black marker and black outlines.

I left the leaves open.
Initially I thought to add some more stamped outlined flowers from the same stampset as the sentiment (Technique Tuesday- Fabulous by Ali Edwards) in the opposite corner, as I now have ranger dye inks to stamp with. Infact I used Cheese puff first for the sentiment, but I didn't like it, also messed  up the stamping, so turned the panel round and stamped with Versafine, I prefer black sentiments for some reason, one being the graphic look of it I suppose.
Mounted the big rose flush with the panel and the smaller ones with one or two layers of foam.
Adhered the cardpanel onto the cardbase with tape runner.
I tired to  match my colours as close as possible to the Stampin Up ones and the photo is quite dark, hideous weather here, but I think I matched them really well. I'm sorry if it doesn;t show...
