Lamp and headlighting arrangement for obtaining a color appearance in an automotive headlight

Lamp suitable for use in an automotive headlight, comprising:

• at least one filament arranged within a transparent lamp vessel, and
• the lamp vessel being bounded at one end of a longitudinal axis of the lamp by a top end and at another end of the longitudinal axis of the lamp by a lower end portion, said lamp vessel comprising:
• a color filter portion through which light is emitted with a color change, said color filter portion being arranged such that a peripheral or a scattered portion of light from said filament is emitted through said color filter portion to achieve a color appearance,
• a color transparent portion through which light is emitted without a color change, said color transparent portion being arranged such that an illumination beam of light is emitted from said filament through said color transparent portion to achieve a non-colored illumination, wherein:
• said color transparent portion, at least for part of the circumference of the lamp vessel, extends between the top end and the lower end portion, and
• said illumination beam of light is emitted in vertical directions forming angles of at least +/−30° with a central plane in which a center of the filament is arranged, the central plane being oriented perpendicular to the longitudinal axis of the lamp.
