howto.md

• Download this extension

https://chrome.google.com/webstore/detail/css-and-javascript-inject/ckddknfdmcemedlmmebildepcmneakaa?utm_source=chrome-app-launcher-info-dialog

• allow it to run it on your crosh tabs by enabling this: chrome://flags/#extensions-on-chrome-urls
• launch a terminal (ctrl-alt-t)
• click the extention's icon and insert the javascript below

voila! now your terminal will always start with these colors

javascript

// Disable bold
term_.prefs_.set('enable-bold', false) 

// Use this for Solarized Dark
term_.prefs_.set('background-color', "#002b36");
term_.prefs_.set('foreground-color', "#839496");

// Solarized Colors
term_.prefs_.set('color-palette-overrides', [
  '#073642', 
  '#dc322f', 
  '#859900', 
  '#b58900', 
  '#268bd2', 
  '#d33682', 
  '#2aa198', 
  '#eee8d5', 
  '#002b36', 
  '#cb4b16', 
  '#586e75', 
  '#657b83', 
  '#839496', 
  '#6c71c4', 
  '#93a1a1', 
  '#fdf6e3'
]);


// set font
var fonts=term_.prefs_.get('font-family');
term_.prefs_.set('font-family', '"Droid Sans Mono", '.concat(fonts));
term_.prefs_.set('background-image', 'url(https://4.bp.blogspot.com/-XrXVg9OJeNo/Vy6mw_pfsJI/AAAAAAAABIQ/nvbsquMq2k431d7M5ekZ0UGL06Kl_41YACLcB/s1600/ecommerce-dark-background.jpg')
    
term_.prefs_.set('environment', {TERM: 'xterm-256color'});
term_.prefs_.set('cursor-blink', true);

Doesn't have any effect for me? Javascript stays associated with crosh tab, but no change in appearance.
