Bouldering Chalk

Bouldering Chalk is the visual language of the modern indoor climbing gym: a dim charcoal-gray plywood cave wall under low warehouse light, dusted with cool magnesium-carbonate chalk and studded with vivid polyurethane holds. The ground is cave-dark; chalk-white is the signature mark.

The system is industrial and graphic — a tight modern sans stack, bolt-grid plywood paneling, and color-graded route holds (yellow, red, blue, green) scattered like a route map. High-contrast labels read crisp on dark surfaces.

Bouldering Chalk 是现代室内攀岩馆的视觉语言：仓库微光下一面深炭灰胶合板"洞穴墙"，洒满冷调的碳酸镁攀岩粉，钉满鲜亮的聚氨酯岩点。底色是洞穴般的暗灰，冷白的攀岩粉是标志性印记，绝不是奶油色或纯白。

整套系统工业而图形化——紧凑的现代无衬线字体组合、螺栓网格的胶合板饰面、像路线图一样散布的彩色岩点（黄、红、蓝、绿）。在深色表面上，高对比度的标签读起来清晰利落。这是室内健身房，而非户外岩壁。
