Change speaker border color on homepage

Trying to change the speaker border color on the homepage.
I have edited the images: avatar_bg.png, speaker_big_bg.png and speaker_small_bg.png (style1)

I have searched css code endlessly it feels.
Orange color code is e89e44

Hi,
probably you have searched in wrong files :

ORANGE style
1) templates/gk_fest/images/style1/speaker_small_bg.png
2) templates/gk_fest/images/style1/speaker_big_bg.png

but you have to know which style you are using because if style2 or style3 - you have to search in those folders!

Violet style
1) templates/gk_fest/images/style2/speaker_small_bg.png
2) templates/gk_fest/images/style2/speaker_big_bg.png

GREEN style
1) templates/gk_fest/images/style3/speaker_small_bg.png
2) templates/gk_fest/images/style3/speaker_big_bg.png

Remember to refresh browser - because it must work, if you choose good files.
I tested this background/border modification few times.

Using style 1 (orange)

Will be revisiting this in a bit, next week we announce the first speaker and then over a month of so we will have five speakers - so I will probably wait until that point versus putting in place the band-aid of less than 5 speakers.
