Override theme's colors

The theme can be customized by overriding one of the theme local variables by setting a list in the spacemacs-theme-custom-colors variable. Here's a list of all the local variables and roles:

There is also explicit colors variables that can be customized:

• aqua
• aqua-bg
• green
• green-bg
• green-bg-s
• cyan
• red
• red-bg
• red-bg-s
• blue
• blue-bg
• blue-bg-s
• magenta
• yellow
• yellow-bg

The green and red colors have two background versions. The green-bg and red-bg are normal light background colors. The green-bg-s, red-bg-s, and blue-bg-s are stronger versions.

Here are some screenshots of the various variables:

If you are using spacemacs, you can put this snippet in your dotspacemacs/user-init to override these colors:

  (custom-set-variables '(spacemacs-theme-custom-colors
                          '((act1 . "#ff0000")
                            (act2 . "#0000ff")
                            (base . "#ffffff"))))

This will override act1, act1 and base to use the specified colors.

Use a custom flycheck fringe bitmap

If you don't use spacemacs and want to get the same look of flycheck fringe bitmap, you can put the following snippet into your init.el (this assumes you are using use-package):

(use-package flycheck
  :init
  (progn
    (define-fringe-bitmap 'my-flycheck-fringe-indicator
      (vector #b00000000
              #b00000000
              #b00000000
              #b00000000
              #b00000000
              #b00000000
              #b00000000
              #b00011100
              #b00111110
              #b00111110
              #b00111110
              #b00011100
              #b00000000
              #b00000000
              #b00000000
              #b00000000
              #b00000000))

    (flycheck-define-error-level 'error
      :severity 2
      :overlay-category 'flycheck-error-overlay
      :fringe-bitmap 'my-flycheck-fringe-indicator
      :fringe-face 'flycheck-fringe-error)

    (flycheck-define-error-level 'warning
      :severity 1
      :overlay-category 'flycheck-warning-overlay
      :fringe-bitmap 'my-flycheck-fringe-indicator
      :fringe-face 'flycheck-fringe-warning)

    (flycheck-define-error-level 'info
      :severity 0
      :overlay-category 'flycheck-info-overlay
      :fringe-bitmap 'my-flycheck-fringe-indicator
      :fringe-face 'flycheck-fringe-info)))
