Painting Around Carpet & Picking a Floor Colour

If you didn't already, now you know my excellent reason for dragging my feet on the basement makeover.  But we're back at it.  Hubby's the wall maker, I'm the wall painter.  There is a tiny area left of the basement left to strip and paint before I can tackle the laundry room.  The carpet might be giving the centipedes a run for their money in the "making this job less fun" category.  I've never lived with carpet (we tore the carpet out upstairs within minutes of taking possession of the townhouse), so painting around carpet is new to me.  It makes me loathe carpet even more.

But I've got this.

In addition to laying down painter's tape, I've been using a wide scraper to push the carpet away so I can neatly edge.  I have a larger edger too (maybe meant for carpets?), but it proved too big and unwieldy so I switched to this.  I've done about 90% of the basement with my scraper pal by my side and it's worked pretty well.  I almost hesitate to ask because it's so late in the game for me: do you have a trick for painting around carpet?

Meanwhile, I'm thinking about what colour to paint the laundry room floor.  It will have the same greige walls as the basement, with black and white textiles (it's a surprise), and industrial-style shelving (I hope).  I had narrowed down the choice to turquoise, orange or raspberry but because of my passion for turquoise, it was an easy choice: something in the green-blue family.  Now I'm thinking . . . do I want a deep teal, a super bright Caribbean turquouise, maybe more of an on-trend emerald hue, or something soft and vintage like mint green?
