None of the colours featured in your two pics

I totally agree with you. GO NEUTRAL. Add colour thru access. I used Hog Bristle. Honestly, book a Colour Consultant thru Dulux or who ever, who will come out and give u the best advise. Dulux Consultant charge about $150, but this is refunded off the paint you purchase. So ur getting expert advise for nothing, if u purchase the paint. Money well spent. I did this and was so glad I did. She will explain where to use what paint, being 1/4, 1/2 or full strength of the chosen colour. I was going to upload photos for you of my rooms, but for some reason this page won't let me. If you would like me to send you photos thru email, I would gladly do so. ir u send ur email address. Good luck.

We do need a photo. What colour is the roof?

first store the dead animals the out of sight and consider Antique USA (white with a grey base) for all the painted walls, plain ceiling white for the plaster ceilings, white semi gloss for all the painted architraves and skirting boards and keep the timber ceilings and timber doors but replace the floral door knobs with plain satin chrome and use simple flat white and satin chrome ceiling fixtures in all the low ceilings and simple pendants in the high ceilings (good variety of both available in major hardware stores) and it would be worthwhile to replace the patterned row of tiles with plain white ( a textured white tile if you can't match the colour) and clean the blockwork walls and the floors look good
