Main problems that need fixing:

1. Cost indicators on the noble cards are too small, and with the style of the black/white borders and the numerals, it's hard to visually scan the nobles and see what colors you need to buy them. Looking at one noble card at a time is not good enough, we want to be able to see the whole collection of nobles and at a glance see, for example, that three of them require green and two of them require black and so on. As it looks now, doing this is visually frustrating and takes too much mental energy.

2. Gem markers at top right of development cards can't be visually distinguished except by color, so if their purpose is to help people with color blindness or whose screen colors are off, they're doing no good now.

3. Color squares with point values at top left often don't have enough contrast with the background, so you have to think for a split second to realize which color it is. At least the numbers at top left (point values) are easy to read now - except on white cards.

4. A major problem that was also a major problem in the old design: Your gem tiles in hand, and development bonus values, are presented too similarly, and it's really hard to remember which is which. Do I have 2 free reds plus one red tile, or is it two red tiles and 1 free red from development cards? Even worse are the colors where you only have one: Is that 1 green tile, or 1 green bonus from cards? It's just hard to keep them straight, even if you know you're likely to forget repeatedly and have to keep trying to examine the screen to figure out which is which. The fact that they're presented so differently on the big screen vs. on the player by player boxes on the side, doesn't help.

Very difficult to read/scan the new graphics; this game requires scanning the cards constantly and the new graphics aren't user-friendly for that. It's much more difficult and not enjoyable to play now. Please make the old graphics accessible, there are many complaints on the forum about this as well. Thank you!

I do not enjoy playing this version. This was the game I like the most. I doubt that I will play until the visuals have been improved.

There is a gradient-like pattern within the circle of gem cost, which makes the numbers difficult to see.
It would be easier to see if you could use solid, single-color circles.

I should also add that when you're selecting gem tiles during your turn, it's nearly impossible to see what the one or two you've already selected are, so if I stop to think and forget what I picked, I usually just have to restart turn and start over. This was a problem in the previous version as well as the new design.

Or better still just let us have the old version back. (This is becoming a repeated request for most things on BGA these days)

No, please do NOT consider the old version the solution. Please read the suggestion. Several of these problems exist in the old version. Although the new design is significantly worse, it already had serious problems before. Please actually fix all of these playability problems. I specifically did NOT ask to go back to the old version in this suggestion (there's another suggestion for that, which I do not support), because it was bad too (although not as bad as the new one).

I've played this game hundreds of times on BGA, and on the table at home. The new design makes it unplayable, sadly.

Please revert to old graphics, while addressing the other concerns.

Please bring back the prior graphics design (the one in use of BGA for many years - first half of 2024 and prior).
That design was perfect. The colors and gem icons were easily, quickly, and nicely distinguishable. The new design takes more effort to distinguish the colors and analyze the cards on the tableau.

That is a valid clarification; I think the below would be the best to make quicker incremental improvement:

Reverting would be the quickest [incremental] improvement; while other valid concerns (with even that old style) could be implemented subsequently as software-development time allows. This strategy dos not "favor" old style, but rather reverts to it first (incremental improvement) as that is quicker (if not relatively "immediate") while other concerns are improved that take more dev time.
