Hello,
I hope you're doing great today.

As I was designing a theme for Code, I noticed what renders is not what I've specified. I know that you may say fonts render with many shading so the final coloring may be changed and that's why I tried every color that I specified and even the background colors rendered incorrectly.

I don't know if it's a feature (which if it is, it's really a bad one) or a bug. If this is a bug I really hope that this issue helps you. But if it's part of the architecture; how it applies to colors and how can I choose a color in a way that after your filter it looks the way I want?

Thanks a lot

I did a bit more of experimenting, It seems that both Code and Sublime renders the colors same way. Why is that so? And how does one get the colors they want in the final render?

I also have tried to understand the filter, The color #141414 renders to #101010 which means:
rgb( 20, 20, 20 ) → rgb( 16, 16, 16 ) so 20% darker but in the #688CB5 to #52749F its: rgb( 104, 140, 181 ) → rgb( 83, 116, 159 ), and reduce ratios are strange:

• 83 / 104 = 0.798076923076923
• 116 / 140 = 0.828571428571429
• 159 / 181 = 0.878453038674033

So I don't think it's just a percent based convertor. And I really can't figure out the process.
Would you please specify it?

@bpasero any idea?

I think I found where the problem was. this link was very good, the problem was with the Gamma RGB and sRGB. It must be added to a documentation somewhere. I compiled my colors to sRGB and it now renders prefect.

TextMate is only available on OS X, so it's no wonder the specification had no explanation, but I guess you have to add it somewhere in your documentation that be very noticeable.

Thanks a lot...
