Are These Textures "Bronze" Enough

[SegFault22]

Are these textures "Bronze" enough - or are they too much red? They could also be somewhat oversaturated or the wrong color, which would need to be fixed. I believe they are fine; but I thought I should ask anyways, considering how important it is to most people that their Bronze should not have too much iron/steel in it, among other significant properties.

The color should not be made too close to yellow, because that color range is reserved for Brass, Aluminium Brass and Invar - those are somewhat different, because they have other colored metals which shift the total color in the opposite way, and thus are only having some amount of yellow and no orange.

Also, can anyone think of a good system which would facilitate ability of colorblind people to still be able to tell what the metal is when looking at the item texture? I could try to write the chemical formula in pixelated letters over the item-image part of the testure, but that would not look good at all, and it would result in problems with the formula of more complex alloys. I could use a grayscale contrast-based system, which would require each metal to be given a unique amount of "roughness", which would be based on how much "rough" the metal is relative to the others; similar to how each metal is required to be given a "false" color enhancement, so that people can quickly tell them apart, and realize which metal is in the ore they are seeing in the half-darkness of a cave or mining tunnel.

The bronze color can be very volatile, because the alliage can be made with many different materials...

It's complicated to say this color is "too" red in my point of view.

This bronze is specifically a mixture of 3 units Copper for each 1 unit Tin. I believe the addition of Tin would make the copper color darker, and the red hue shift helps differentiate it from just copper. It is also possible that the color of copper is not enough orange, causing the bronze to look wrong. I have included this image to compare the two:


I will use specific ratios for the alloys, some of which require tiny amounts of some metals relative to much larger amounts of other metals in the mixture. Brass would be a mixture of 3 units Copper for each 1 unit Zinc, and I will make its texture a little closer to yellow than pure copper.

Therefore I plan to use a system based on division into ninths (and occasionally fourths), so that it is possible to accurately mix the materials with a crafting grid and create extremely complex combinations. There will have to be small (1/4th) and tiny (1/9th) piles of dust - and possibly even smaller amounts like pinch (1/81th), speck (1/729th) and grain (1/6561th) for extreme ratios, if it ever gets that complex.
I want all of the alloys to be distinguishable from other alloys or pure metals, by their color - but it is okay if alloys with very similar constituent materials have a similar or almost identical color, depending on how much difference there is between the mixtures.
