## 1 Introduction
Laser ablation can be considered one of the most efficient techniques to directly produce superhydrophobic surfaces on a wide range of materials [41]. By optimizing the laser processing parameters, it is possible to produce robust 3D structures that are necessary to prolong the durability of the processed surfaces [42]. Femtosecond lasers have been used dominantly to produce nanostructures on different metal surfaces to alter their wettability behavior. Following laser ablation, processed surfaces may initially behave as superhydrophilic, but when kept in ambient air for many days, they transform into super-hydrophobic ones with very small contact angle hysteresis that makes them suitable for a wide range of technological and bio-medical applications [43]. Some divergences of aging-dependent contact angle hysteresis were observed for surfaces processed by femtosecond pulses compared to those processed by nanosecond pulses [44; 45]. Superhydrophobicity of laser-ablated surfaces is attributed to the surface chemistry and topography of the processed surface [29; 46]. The ultimate degree of the achieved superhydrophobicity depends on the produced surface roughness. Furthermore, the changes in the wettability behavior of the air-exposed laser-processed surfaces can be also attributed to the increase of carbon content and decrease of surface polarity due to chemisorbed organic substances from the air moisture [47]. The important issue of all these laser processing procedures is their duration. In most of the above-considered cases, the used lasers operate at pulse repetition rates in the range of tens Hz to a few kHz, which results in a relatively slow speed of processing the surfaces. The application of advanced high pulse repetition rate lasers (i.e. those operating at \(>\)100 kHz regime) along with high scanning speed (i.e. \(>\)100 mm/s) can significantly accelerate the modification of coloring and wettability properties of materials. To operate with such class lasers for LIPSS formation, one has to deal with \begin{table}

Once a robust methodology of laser-matter interaction at these high pulse repetition rate conditions is developed, the processing time of coloring and wettability modifications can be decreased by orders of magnitude, which will make it attractive for industrial applications. In this work we used 150 kHz laser for LIPSS formation and describe methods here for optimizing such a high pulse repetition rate regime of the laser-matter interaction that leads to modifying the coloring and wettability properties of the developed surfaces. We show how nanostructures produced by ultra-short laser pulses can change the optical diffractive effects leading to the generation of angle-dependent colors on steel, copper, aluminum, and brass surfaces. We present a simple process of re-coloring of aluminum to prove the sustainability and reusability of the processed samples. We analyzed the wettability properties of such surfaces and demonstrate the relation between these properties and the lasting coloring of surfaces. We also demonstrate how a superhydrophobic aluminum surface can be developed by femtosecond laser processing when stored in vacuum for several hours after the laser treatment.
