Materia-theme: [Accessibility] Update primary color for light variants

[nana-4]

I've been feeling that the current primary color for light variants (#4285F4) is sometimes a bit too bright. Especially it's noticeable where the color is used for text.

The contrast ratio between #4285F4 and #FFFFFF is 3.56:1. It doesn't pass the WCAG's passing score 4.5:1 which Material Design recommends.

We probably need a little darker primary color. Ideally it should pass the WCAG's level AA.

I have 2 colors that I'm considering as a candidate:

1. #1A73E8

• The contrast ratio is 4.51:1.
• Used in many Google products.
• Might be too dark/vivid?

1. #3B78E7

• The contrast ratio is 4.18:1.
• Softer than the above.
• Doesn't pass the WCAG level AA.

I'm leaning toward the former, because it passes Level AA.

#1A73E8 is "pixel blue", right?
It's got my vote (for what it's worth)

I also like #1A73E8, again for what it's worth. Thank you for your work.

I also like #1A73E8. It makes blue so blue :)

Thanks for your feedback! I've changed the primary color to #1A73E8 in master :)

By the way, this is not a final decision. If I got many complaints about the new primary color, I will consider another color :) So I'm going to keep this issue open for a while.

I'm obviously in the minority here, so I'll share my thoughts...

1A73E8 is a great color. But it seems a bit too "cartoonish" and reminds me of the blue used in Windows 95; in other words, it doesn't feel very sophisticated.

Are there any other options to meet the 4.5:1 contrast ratio requirement, but still have a more professional or refined look?

(As always, I truly appreciate all the hard work put into this wonderful theme!).

@PJSingh5000 Thanks for your feedback.

I opened this issue because of concerns similar to yours :)

At first I felt #1A73E8 is a bit too strong and could be annoying. However after using it for a few weeks, I became very happy with it. Now it looks more professional and refined look to me.

I personally have relatively good eyesight, but that color benefited even me: It made it easier to work away from display. And I have less to bring my face close to the display.

It's probably a matter of getting used to it, I guess.

Contrary to my expectation, there was little or nothing objection against this change.

Again, I'm very happy with this change - it's much easier to see 🙂

So I'm going to close this issue.
