var	role
act1	One of mode-line's active colors.
act2	The other active color of mode-line.
base	The basic color of normal text.
base-dim	A dimmer version of the normal text color.

cblk	A code block color. Used in org's code blocks.
cblk-bg	The background color of a code block.
cblk-ln	A code block header line.
cblk-ln-bg	The background of a code block header line.
cursor	The cursor/point color.
const	A constant.
comment	A comment.
comment-bg	The background color of a comment. To disable this, customize spacemacs-theme-comment-bg.
comp	A complementary color.
err	errors.
func	functions.
head1	Level 1 of a heading. Used in org's headings.
head1-bg	The background of level 2 headings. To disable this, customize spacemacs-theme-org-highlight.

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)))
