Summary:
Slabs appear 1-2 light levels lower than surrounding full blocks, stairs etc.
Steps to Reproduce (Slab):
Place a full block and upper slab of any type side by side
Note that the slab appears darker than the full block
Place a torch on the slab
Note that the slab brightens to match the full block
Steps to Reproduce (Stair):
Place 3 full block towers 1 block apart (smooth sandstone works best)
Place stairs in between to make a square (like many window designs - example below)
Note that the stairs appears darker than the full block
Note: Smooth sandstone is apparent at all times of day however my testing showed that all stair types are affected but most only show at night. Example below.
What I expected to happen was...:
Slabs, stairs and full blocks should react to ambient lighting in the same way.
What actually happened was...:
Slabs, stairs and full blocks each react differently to lighting causing them not to match.
I've not been able to replicate the reports of differences with walls. If this still exists please comment back below with instructions on how to demonstrate the issue.

I believe this to be due to slabs and stairs allowing light to pass through on Bedrock.
Asked a lucky friend with an RTX card to test on the RTX beta (but with ray tracing mode switched off) as Render Dragon was supposed to change that and (despite RTX being listed as an affected version) it is not affected in both RTX on and off modes.
So RTX is not affected and Render Dragon appears to fix this particular issue.

This is probably a bug cause the old version of Minecraft, the slabs, stairs and walls were the same colour as it's block. I hope it gets fixed cause I am currently building Hogwarts and it requires a lot of slabs, stairs and walls, placing in these to round things off, it doesn't look round cause they are dark. Hopefully, it gets fixed and my arches and curves looks better on my Hogwarts with the blocks the same colour.

Still no news on this, my builds look disgusting now, please fix it soon.
SlimySpeck
I think it's because lights can pass through stairs because lights can't pass through slabs anymore

it has been over a year, game is all about building, and this small bug causes a big eye sore in building projects, please fix this, especially when you are working with light coloured blocks like sandstone, please fix this asap
migrated
Still not fix in 1.17.2

@Varun Jaiswal. True
This still exists in 1.17.2 bedrock

This happened on the bank I was building out of quartz, Please fix.

This is still occurring in 1.19. Looks like it's been about 3 years since this issue has been reported. Has there been any acknowledgement on Mojang's part?
migrated
Still not fixed, might as well bump this issue lol

Noticed this when working with Cut Red Sandstone.
Simply wanted a higher durability variant by turning some to slabs.

The issue is actually the exact opposite; The BLOCKS appear lighter than their slab/stair counterparts.

I think this title is wrong. It’s not that they are darker or lighter, it’s the shading! It’s something wrong in how the game interprets slabs etc, like it doesn’t really know how to correctly apply shading on the blocks. The full blocks look great, in any light, while the partial blocks look weird as soon as the light is less then full. 100% is light straight on, and then the sides are calculated with some algorithm counting ambient light as well. Something is off in the games counting.
In some very tricky lighting the sandstone slabs really don’t know how to look. Check this out. First block is a full block, the rest is slabs.

lol they are trying so hard to be smooth!

This might be similar to MCPE-178976 which is about smooth lighting not working correctly on some non-full blocks. This also includes the slabs and stairs that the reporter mentioned.

The image I attached as of 2024, July 7th, features the blocks while I"m under the effects of night vision.

This is still happening in v1.21.2 and is easily reproducible with sandstone stairs.
