inline const Color &operator[](size_t i) const

Access the members of the palette as an array

Parameters

i – Index of the desired element, i must be less than size()

inline size_t size() const

Returns the number of colors in the palette

inline const_iterator begin() const

Returns an iterator to the first item in the palette

inline const_iterator end() const

Returns an iterator to after the last item in the palette

inline bool operator==(const Palette &other) const

Compares two palettes for equality (whether they contain the same colors)

virtual bool getColorBlindFriendly() const = 0

Returns whether the palette is confirmed as suitable for colorblind viewers

virtual Category getCategory() const = 0
