Ideas to Improve Concrete Ramp

Hi, first time posting so hope it comes out ok. Due to access needs I now have this concrete ramp in the front garden. I would love to add some greenery but struggling to see how to do this. There are some very very small gaps along the middle of the ramp. Are there any plants that might cope in such a small space?
Any ideas welcome, the ramp does need to stay though

1. Is there any soil in those cracks or is it just hardcore or concrete at the bottom of them?
2. If there is soil, then it will be very dry unless watered regularly and, with the water coming into contact with the concrete slabs, will probably be very alkaline.
3. Any plants that could manage to gain a foothold would need to be very slim, slender and non twiggy. You don’t want to get tangled up in sticks and thorns.
As a last resort, you could buy a couple of packets of mixed annual seeds and sprinkle them around. Some are bound to survive and flower.
If there's a border in front of the white wall you could plant in there to soften it a little.

Pelargoniums might be a good choice to grow - they prefer not to be too wet and flower constantly throughout the summer and beyond if it remains mild.
I took this photo in Spain over 10 years ago of Pelargoniums in balcony pots which impressed me!

Delosperma (there are various colours), would probably also work, and Sempervivum. Creeping Thyme should also work. Personally I would avoid anything bigger/annuals, as they will probably need too much regular watering.
I would also consider painting the ramp with a suitable masonry paint, perhaps a Sage green, or something similar, just to soften it. If you won't want to do the whole ramp, then you could just paint the blocks at the sides of the ramp. Agree with those that suggested painting the rails as well.
KeenOnGreens advice sounds good too.
I know cost might be an issue but you could get a contractor to lay some resin bound gravel on top of the concrete to create something a bit softer.
Possibly add a matching triangular pot - if it doesn’t impair your turning circle - in that first corner with a tall, flowering perennial that could then be echoed by using the same plant either side of your bay window. For the latter keep it simple, maybe the old favourite Verbena Bonariensis would work - tall, easy, non-spiky, long-flowering and drought tolerant. Or Lavender perhaps?
That way, the whole looks designed and planned rather than an attempt to disguise!
Would it be possible to plant low growing climbers in the garden to train up lightweight fencing against the rails?
